Traditional variation analysis methods are considered to be "rigid-body" or "non-compliant" modeling; meaning, that every part within the assembly does not flex or would not be distorted through an assembly process such as welding, clamping or unclamping of an assembly fixture.
While this might be the case with a few machined components, most commodities and materials like sheet metal, plastics, aluminum, etc. can be heavily influenced through the manufacturing processes (both fabrication and assembly), thus changing the dimensional integrity or shape of the part/assembly. Finite Element Analysis (FEA) is used to determine the stresses and displacements in mechanical objects and systems and is the basis for this leading-edge advancement in predictive analysis.
3DCS FEA Compliant Modeler, an add-on module to the 3DCS software solutions, utilizes FEA methods to accurately simulate the variation of compliant parts and assemblies within the 3D Variation Analysis model.

Worst Case Tolerance Analysis - What is it, why do it, and how?Benjamin Reese
From the DCS Webinar on Worst Case: http://mkt.3dcs.com/worst-case-tolerance-analysis-webinar
Worst Case tolerance analysis is where each individual tolerance is set to a point in its range (typically a tolerance limit) where it will result in either the maximum or minimum output at a specific measured location.
A Worst Case analysis is the only way to guarantee that an assembly of good detail parts will not be out of specification.
However, in most cases, a statistical analysis gives the results needed to make decisions and reduce manufacturing costs.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

What is Compliant Modeler?
Compliant Modeler is an add-on module for 3DCS Variation Analyst Software.
Compliant Modeler uses mesh files from an FEA Preprocessor to simulate the
effects on parts and materials from processes, both environmental processes like
gravity and heat, as well as manufacturing processes like welding, clamping, bolting
and riveting.
Compliant Modeler solves the deformation as part of the variation analysis, adding
the variation from deformation and process to the stack up.
Using a Stiffness Matrix from a Solver, 3DCS simulates the deformation from the
process in conjunction with your Variation Analysis.

FEA Mesh Files
Compliant Modeler allows the user to apply an FEA Mesh file to a part or multiple parts.
• These need to be generated from an FEA Software.
• The FEA Software is not needed for any analysis
Once the Mesh file is applied to the part, Compliant Moves are added to simulate different
kinds of processes and forces.
The Deformation changes the nominal position, allowing further tolerance analysis stack

COMPLIANT MODELER BEST PRACTICES
Tips on using Compliant Modeler
30. Dimensional Control Systems | 2017 All Rights Reserved
Mesh File Creation
NOTE: Mesh file should
be created by an FEA
specialist.
•You need an individual mesh file for each
compliant part in the DCS model.
One Part, One
Mesh File
•If modelling an assembly as one part then the
mesh file needs to be created as an assembly
with connections between parts in the
assembly.
If Assembly is 1
Part, Then Mesh
Needs to be an
Assembly
•Number of nodes per part can be judged
based on part geometry. Increasing number of
nodes per part might increase the accuracy
but can result in slower simulation time.
More Nodes, More
Accuracy, More
Time Simulating
Optimum mesh file
size is 10mb or less.
The part mesh file from
an FEA pre processor
does not need to have
any boundary
conditions. DCS creates
boundary conditions.
31. Dimensional Control Systems | 2017 All Rights Reserved
Modeling Best Practices
First step is creating the whole model including
all MTMs! (Moves, Tolerances, Measures)
Build Rigid Body First Then Add Compliant Moves
32. Dimensional Control Systems | 2017 All Rights Reserved
Modeling Best Practices
● While writing compliant moves, all compliant parts should be fully constrained before
doing any further operation such as Weld, Forces, Thermal, Gravity etc. A part can be fully
constrained using:
o One point in a Hard/Coincident Clamp Move (using 6dof FEA files)
o Three points in a Hard/Coincident Clamp Move (using 3dof FEA files)
o 6 points in a Soft Clamp Move.
o Position 3 points(1 point in 6dof) having x, y & z checked.
● It is recommended not to mix and match Hard and Soft clamp in one move.
33. Dimensional Control Systems | 2017 All Rights Reserved
Thermal Best Practices
If simulating thermal deformation, create your thermal move and pick all the points that
have a thermal deformation and input the change in temperature.
Check the thermal move section in help file to understand the difference of having a
thermal deformation on whole part and on some points on the part.
34. Dimensional Control Systems | 2017 All Rights Reserved
Clamping Best Practices
While unclamping/unpositioning, need to make sure the assembly/parts are still fully
constrained after unclamping/unpositioning.
When simulating a multi-stage assembly, unclamping must be a 2 move process.
In the first move you unclamp all but the points needed to fully constrain the assembly and
then use Skip Deformation option in an Unclamp Move for remaining clamps.
Skip Deformation option removes the clamps from the software memory but does not
deform the part.
Skip Deformation Unclamp Move should be the last move in the 1st fixture stage.
35. Dimensional Control Systems | 2017 All Rights Reserved
FEA Mesh Creation Best Practices
Make sure the FEA files are supported by stiffgen/Compliant Modeler!
Refer to help file for supported files.

FEA Mesh Creation Best Practices
● Make sure consistency of units is maintained while creating the mesh file. For
reference to consistency of units see the DCS help file.
● If using Stiffgen to create the FEA files then select the mesh file units in stiffgen.
● If you have multiple FEA solvers available on your machine, make sure to select the
same FEA solver that was used as a pre-processor for creating mesh file.
● It is recommended to create 6 Degree of Freedom (DoF) FEA files for a shell mesh.
● You can only create a 3 Degree of Freedom (DoF) FEA file for a solid mesh.
37. Dimensional Control Systems | 2017 All Rights Reserved
FEA Mesh Creation Best Practices
● Select Mass Matrix/Thermal load option in stiffgen if you have Gravity or Thermal
Expansion resp. in your model.
● It is recommended to always have a 6 Degree of Freedom (DoF) thermal load file for shell
mesh.
● Once you hit Generate FEA Files, make sure the batch process ran successfully and the files
were generated. If you see an error then check the .dat or .msg files in the dcsFEA_DATA
folder for any error messages.
For Thermal / Gravity
38. Dimensional Control Systems | 2017 All Rights Reserved
Nominal Build Best Practices
1. Create the Input FEA Data move and select all the compliant parts and corresponding
mesh/stiffness files in it. Move it above all the compliant moves in the tree.
2. Deactivate all the compliant moves and hit nominal build and check all the DCS points are
linked to FEA nodes using FEA Point Linking Wizard.
3. If everything looks good, activate all the compliant moves and hit nominal build again.
4. If you have any unrealistic deformation of points in the model, make sure to check the
consistency of units in FEA files.
