A typical way to create simulation strategy
4
We can teach our customers how to use numerical simulation tools to
solve their industry-specific problems.
At the same time we ourselves are learning more about specific kinds of
problems and solutions.
Thus, our engineers have knowledge about:
• Bridges aero elasticity
• Hydro power plant segment water seal
• Corrugated cardboard box crush test
• …

How can we share the methodology with the customer?
5
Simulation methodology can be shared via:
• Text reports and papers
• Step-by-step user guides
• Customer-specific trainings
• Workflow in the ANSYS Workbench environment
We can share more value with our customers!

Weaknesses of the traditional strategy: can we do better?
6
• Considerable training time spent while using text report
• Ensuring compatibility of software versions
• Language barrier
• Number of trained engineers may eventually be reduced
• Weak protection from human errors
• High qualification of the customer’s engineers is required
• Leakage of confidential information
• Routine operations take time

Yes, we can!
7
• Use methodology in an interactive way
• Reducing training time
• Run simulation as a web application
• Ensuring compatibility of software versions
• No language barrier
• Number of trained engineers may be reduced
• Access control and security
• Protection from human errors
• Avoiding leakage of confidential information
• Hiding sophisticated controls and user interface simplification
• Democratization of simulation
• Running “what-if” analysis at the earliest stages of the product development
• No routine operations

Simulation challenges
10
• A large number of design layouts and topologies
• Various types of analysis:
• fire-resistance
• strength
• signal integrity
• Cable transit should be manufactured with high precision
• Direct simulation approach takes too much time
• Insufficient skill level of the customer engineers

3D model automated generation
11
• Design layouts and topologies
cannot be parameterized in DM
• 3D model generation procedure
includes conditional operations
and cycles
• JScript macro developed

New criteria for all analysis types
13
• General
• Geometry simplification
• Mechanical
• Transient simulation replaced by
steady-state
• Nonlinear material replaced by linear
• Loading conditions changed
• Signal integrity
• Transient simulation replaced by
harmonic analysis
