Clamp force is an important factor when designing plastic parts. The Analysis Consulting team at Hawk Ridge Systems worked with Stamco Specialty Tool to identify whether or not a design could be molded, and clamp tonnage was the main goal. Watch the webinar here: http://bit.ly/1BcJa1J
If you’re the sole user of SOLIDWORKS at your company or you’re a solo operator, choosing an installation method is straight forward: install SOLIDWORKS through the SOLIDWORKS Installation manager. But once you add a few more users or multiple sites into the mix , you really have to start thinking about the other methods that are available.

Design Analysis - Planning for Your Next SOLIDWORKS Simulation ProjectHawk Ridge Systems
Have you ever started a SOLIDWORKS Simulation analysis that you thought was pretty straightforward, but after 6 months (including several missed deadlines and scope changes) ended up right back where you started? Well, you aren't alone. One of the main topics we teach in our Analysis Mentoring sessions is how to properly plan your analysis before you start, which will increase your productivity and minimize headaches down the road.
When you have more SolidWorks users than you have SolidWorks licenses, or if you need to share a particular add-on among multiple users, using network/floating licenses is the way to go. What if you could do the same with the hardware needed to run SolidWorks – without having to physically move the hardware to the user or the user the hardware? What if there was a way to move SolidWorks into the cloud to increase its impact on your organization? This is where NVIDIA GRID VCA comes into play. GRID VCA is a network appliance that allows you to use SolidWorks from anywhere and anytime from Windows, MAC, or Linux with the same level of performance that you’re used to with your current, conventional desktop solution. Join Product Manager Jared Conway for an in-depth look at this cutting-edge technology that brings SolidWorks 2014 to the cloud.

Comparative analysis between traditional aquaponics and reconstructed aquapon...bijceesjournal
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

Product Design Trends in 2024 | Teenage EngineeringsPixeldarts
The realm of product design is a constantly changing environment where technology and style intersect.

In this piece, we delve into the significant trends set to influence the look and functionality of product design in the year 2024.
How Race, Age and Gender Shape Attitudes Towards Mental HealthThinkNow
Mental health has been in the news quite a bit lately. Dozens of U.S. states are currently suing Meta for contributing to the youth mental health crisis by inserting addictive features into their products, while the U.S. Surgeon General is touring the nation to bring awareness to the growing epidemic of loneliness and isolation. The country has endured periods of low national morale, such as in the 1970s when high inflation and the energy crisis worsened public sentiment following the Vietnam War. The current mood, however, feels different. Gallup recently reported that national mental health is at an all-time low, with few bright spots to lift spirits.
To better understand how Americans are feeling and their attitudes towards mental health in general, ThinkNow conducted a nationally representative quantitative survey of 1,500 respondents and found some interesting differences among ethnic, age and gender groups.
Technology
For example, 52% agree that technology and social media have a negative impact on mental health, but when broken out by race, 61% of Whites felt technology had a negative effect, and only 48% of Hispanics thought it did.
While technology has helped us keep in touch with friends and family in faraway places, it appears to have degraded our ability to connect in person. Staying connected online is a double-edged sword since the same news feed that brings us pictures of the grandkids and fluffy kittens also feeds us news about the wars in Israel and Ukraine, the dysfunction in Washington, the latest mass shooting and the climate crisis.
Hispanics may have a built-in defense against the isolation technology breeds, owing to their large, multigenerational households, strong social support systems, and tendency to use social media to stay connected with relatives abroad.
Age and Gender
When asked how individuals rate their mental health, men rate it higher than women by 11 percentage points, and Baby Boomers rank it highest at 83%, saying it’s good or excellent vs. 57% of Gen Z saying the same.
Gen Z spends the most amount of time on social media, so the notion that social media negatively affects mental health appears to be correlated. Unfortunately, Gen Z is also the generation that’s least comfortable discussing mental health concerns with healthcare professionals. Only 40% of them state they’re comfortable discussing their issues with a professional compared to 60% of Millennials and 65% of Boomers.
Race Affects Attitudes
As seen in previous research conducted by ThinkNow, Asian Americans lag other groups when it comes to awareness of mental health issues. Twenty-four percent of Asian Americans believe that having a mental health issue is a sign of weakness compared to the 16% average for all groups. Asians are also considerably less likely to be aware of mental health services in their communities (42% vs. 55%) and most likely to seek out information on social media (51% vs. 35%).
AI Trends in Creative Operations 2024 by Artwork Flow.pdfmarketingartwork
Creative operations teams expect increased AI use in 2024. Currently, over half of tasks are not AI-enabled, but this is expected to decrease in the coming year. ChatGPT is the most popular AI tool currently. Business leaders are more actively exploring AI benefits than individual contributors. Most respondents do not believe AI will impact workforce size in 2024. However, some inhibitions still exist around AI accuracy and lack of understanding. Creatives primarily want to use AI to save time on mundane tasks and boost productivity.
Organizational culture includes values, norms, systems, symbols, language, assumptions, beliefs, and habits that influence employee behaviors and how people interpret those behaviors. It is important because culture can help or hinder a company's success. Some key aspects of Netflix's culture that help it achieve results include hiring smartly so every position has stars, focusing on attitude over just aptitude, and having a strict policy against peacocks, whiners, and jerks.

Google's Just Not That Into You: Understanding Core Updates & Search IntentLily Ray
1. Core updates from Google periodically change how its algorithms assess and rank websites and pages. This can impact rankings through shifts in user intent, site quality issues being caught up to, world events influencing queries, and overhauls to search like the E-A-T framework.
2. There are many possible user intents beyond just transactional, navigational and informational. Identifying intent shifts is important during core updates. Sites may need to optimize for new intents through different content types and sections.
3. Responding effectively to core updates requires analyzing "before and after" data to understand changes, identifying new intents or page types, and ensuring content matches appropriate intents across video, images, knowledge graphs and more.

Materials Definition
• Start your mathematical
problem with a strong base.
• Common area of mistakes in
FEA problems
• The source for SOLIDWORKS
material properties is Metals
Handbook Desk Edition (2nd
Edition), ASM International.
13. 13
Custom Materials
•The default SOLIDWORKS material database cannot be
modified. This is by design.
•When creating a custom material, it is recommended to copy
an existing (similar) material, and modify.
16. 16
Solid Elements
•Basic shape is a tetrahedron
•High Quality (default) Solid Elements will have 10
nodes: 4 corner nodes and 6 mid-side nodes. Edges
of HQ elements can better map curvilinear shapes.
•Draft Quality Solid Elements have 4 corner nodes
and linear edges.
•For both cases, each node has three degrees of
freedom, all translational.

Total DOF 12 30
17. 17
Shell Elements
•Used for thin geometry
•Basic shape is a triangle
•High quality (default) Shell elements have 6 nodes: 3 corner
and 3 mid-side with 6 DOF per node (including rotational
freedom). Can better map to curvilinear shapes.
•Draft quality Shell elements have 3 nodes (corners only), with
6 DOF per node. They remain linear through deformation.
Draft High
Nodes 3 6
DOF per node 6 6
Total DOF 18 36
18. 18
Element Quality
Draft quality mesh will create an
analysis with the same fundamental
mesh structure, but less nodes/DOFs
Stress results will likely not be
accurate enough for final results
However, draft mesh is an excellent
tool for model preparation or
troubleshooting
19. 19
Why Use Shell Elements?
•Any model could be meshed with Solid Elements. However, to
get an adequate mesh for thin objects, the number of elements
can become unmanageable. More DOF = Longer Solve Time!

Beam Elements
•Used for slender objects with a constant cross-sectional
shape
• As of SOLIDWORKS 2011, tapered beams also supported

21. 21
Invalid for Beam Elements
•Beam elements support tapered
beams, but cross-section can only
shrink or grow proportionally
•For other invalid beams, see the
help file article titled: “Invalid
Tapered Beams”
24. 24
Global Contact
•Bonded- Selected components or bodies behave as if they
were welded during simulation (no relative translation or
rotation).
•Allow Penetration – Selected components or bodies may
pass through each other.
•No Penetration-Selected components or bodies do not
penetrate each other during simulation. Surface to surface
contact formulation is applied by default.
25. 25
Global Contact Limitations
•Global contact will only be applied to
faces/entities that are coincident at the
start of the analysis.
(2014 allows some non-touching faces
in global contact, but have had limited
success with this function)
•Mixed mesh types: global bonded
contact does not always automatically
create connections
•Solution: Local Contact Sets!
26. 26
Contact Tools and Tips
• Interference detection – “Treat coincidence as interference”
does a great job of showing where parts are initially touching
• Contact Visualization Plot – New in SW2014, allows you to
visualize what contact has been created, and what type.
• Solver-based contact visualization will show contact
relationships between mesh elements.
28. 28
Fixtures
Used to represent how the given model is
attached to the rest of the world
– Fixed on a Surface, Edge or Point
– Free Sliding or Rotation
Helpful for reducing the size of the problem
to a component level or subassembly level
Ensures the problem is in static equilibrium
Remove DOF in the model
29. 29
Degrees of Freedom
• Objects in 3-D space have 6 degrees of freedom (DOF)
•In Cartesian coordinates, there are:
•Three translational (x,y,z)
•Three rotational (about x, about y, about z)
• In SOLIDWORKS Simulation, the conditions of the
problem (fixtures, contact, mesh) determine how many
total DOF exist
• More DOF means a more complex problem,
requiring more computer resources

Defined in units of force (lbf, N) Defined in units of force per area (psi, N/m2)
Can be applied to faces, edges and
vertices
Can only be applied to faces
Can be applied normal to face or in
specified direction
Can be applied normal to face or in specified
direction
Components can be defined in all 3
vectors (local x,y,z)
Can only be defined in one vector
By default, Force values are distributed across the selected
geometry, while Pressure values are constant over the selected
geometry
35. 35
Force vs. Pressure.
Forces and Pressures can both represent the same load depending
on how you define them!
100 lbf / 1 in2 = 100 psi
100 psi * 1 in2 = 100 lbf
36. 36
Remote Mass vs. Distributed Mass
Two differences:
1. Remote mass adds stiffness to the model
as the component being replaced by the
remote mass is considered to be attached
by rigid bars.
2. The remote mass can have a non-uniform
distribution whereas the distributed mass
is always uniformly applied.
Please note: "Treat as remote mass" only considers
mass…so be sure to define gravity!

Mesh Creation Tools
• Two mesh creation schemes – Standard and Curvature-Based
• Generally, Curvature-Based will create more elements, but better adapt
to complex geometry
• Curvature-based mesher takes greater advantage of multi-core CPUs

Mesh Convergence Practices
In stress analysis the quality of the result is directly dependent on the
quality of the mesh.
No stress result should be accepted as “correct” until you’ve proved that
the mesh is adequate.
This is done by proving that the stress results are “converged”
48. 48
What is Convergence?
• All FEA analysis is based on the concept of
discretization- breaking a model into individual pieces
that can be calculated (meshing).
• This inherently adds error to results- convergence is
the process of reducing mesh error
49. 49
Checking Strategies
Methods:
1. Manual Inspection
a) Run a Study > Refine Mesh > Review
Results (stress)
b) Utilize Trend Tracker
2. Design Study
a) Create a parameter linked to mesh
control or Global mesh size
b) Manually specify sizes or use
Optimization
3. Adaptive Meshing
50. 50
Checking Convergence – Manual Inspection
1. Run an analysis
2. Increase mesh density (either globally or locally)
3. Review key results
4. Repeat until key results don’t change within an acceptable
tolerance
51. 51
Checking Convergence – Adaptive Meshing
•The h-Method
•The concept of the h-method is to use smaller elements.
After running the study and estimating errors, the software
automatically reduces the element size in appropriate
areas.
•The p-Method
•The concept of the p-method is to add more nodes and
increasing the order of the element in regions with high
errors. After running analysis and estimating errors, the
program increases the order of elements in regions where
necessary.
52. Adaptive Finite Element Analysis
h-Adaptivity, p-Adaptivity
Refining the mesh (h-Adaptivity)
Changing the “order” of elements (p-
Adaptivity)
1st order
(Draft Quality)
2nd order
(High Quality)
… 5th order
53. 53
Concentrations & Singularities
No Singularity Singularities
No sharp geometrical discontinuity and
no concentrated load/fixture
Sharp geometrical discontinuity or
concentrated load/fixture
Will converge when mesh is refined Will not converge with refinement
Converged stress value can be trusted Stress values cannot be trusted
•Stress concentrations are areas of high stress
•Stress singularities are a type of concentration that displays
unrealistically high stress values due to mathematical phenomena
(displacements are not affected)
•Singularities generally occur in sharp corners

Matching Real-Life Results
•What are the SOLIDWORKS Simulation results
being compared to?
-Hand calculations?
-Experimental results?
-Other software?
56. 56
Hand Calculation Example
Stress/Strain calculation used to evaluate deformation of tank wall
under pressure
Formula predicts 0.485in, SOLIDWORKS predicts 0.501in for a single
plate.
However, once you add the other 3 walls, displacement is 0.19in
The 3d case is closer to fixed support than simple support.
57. 57
Matching Real-Life Results: Conditions
•Are you comparing to physical tests,
or real-world usage?
•Do you have a document that
explains the experiment setup?
•What materials are being used? Do
the mechanical properties of your
material match that which is found in
the SOLIDWORKS material
database?
•How realistic are your
restraints/fixtures?
58. 58
Matching Real-Life Results: Loads
•Are you running the correct study? A static load
of value x may cause an object to react much
different than an impact load of value x.
•Are there other factors that you are omitting in
your analysis?
•Gravity
•Friction
•Damping

How to have confidence in results?
Validation examples
NAFEMS is an independent, not-for-profit organization
that sets and maintains standards in computer-
aided engineering analysis and, specifically, finite
element analysis (FEA).
62. 63
Matching Real-Life Results
• Remember: when using FEA, the end goal should not
always be to duplicate real world results.
• Garbage in, garbage out
• Significant value can come when using it to get relative
results (Trend studies, design decisions).

• Printed Circuit Board properties with the Electronic Cooling Module
69. 70
Flow Simulation: Goals & Solving
•Goals allow easy checking of key results
both during and after the simulation
•Verify what you’re trying to measure:
average vs. bulk average
•Ensure a certain level of accuracy in the
solver- “convergence”
•Solver can be run on local machine, or
on network- will use all available CPU
cores
70. 71
Flow Simulation: Results
•Both numerical and visual results are available to evaluate
design
Typical workflow:
1. Check if requirements are met via Goals, surface
parameters, etc.
1. Max CPU Temp? Pressure Drop?
2. Use Cut Plots, Surface Plots, Flow Trajectories to see
why, and how design should be modified.
