Running the Validation

You must verify that an analysis of your base model generates the expected results before you continue the optimization.

Before you begin: Open the Topology Optimization assistant. See Performing an Optimization Using the Topology Optimization Assistant.

About Setup Validation
  1. From the Validation section, select Setup validation.
  2. Click Run.
  3. Choose the Location where the optimization (simulation) runs:
    OptionDescription
    Local Runs the simulation on the private 3DOrchestrate Station on your computer.
    Cloud Runs on a Dassault Systèmes cloud server if your company has purchased a cloud role and licensing. Licensing credits are always consumed when using a cloud server to cover the cloud infrastructure cost.
    Remote Runs through 3DOrchestrate if your system administrator has configured this infrastructure in your on-premises 3DEXPERIENCE platform. Click to choose 3DOrchestrate options such as where your simulation runs; see About Remote Simulate Options for 3DOrchestrate.
    Local interactive Runs locally on your computer without using 3DOrchestrate. If you select this method, keep the native client active throughout the simulation.

    For more information, see About Locations for Running Simulations.

  4. Select the license type.
    OptionDescription
    Embedded

    Runs the simulation on on-premises computers provided by your company, with a separate licensing mechanism that does not require any additional credits or tokens.

    When available, embedded licensing is always used first to reduce the number of credits or tokens required. While an embedded license simulation is running, additional concurrent simulations can be run using credit or token licensing.

    Credits

    Runs the simulation using license credits. Credits are one-time consumable licensing items that you can use to run the simulation.

    Tokens

    Runs the simulation using license tokens. Tokens are suitable for sustained simulation workloads over the license term.

    For more information, see About Simulation Licensing Schemes.

  5. Optional: Adjust the Performance (speed) of simulation runs.

    As you increase the requested performance, the simulation finishes faster but requires additional tokens or consumes credits at a faster rate. The 3DEXPERIENCE platform estimates the baseline number of processor cores required to run your simulation, based on the model size and degrees of freedom. The baseline number of cores is doubled for each increment of the performance setting to determine how many processor cores are used.

  6. To start the validation, click OK.
    Functional Generative Design runs a static perturbation analysis of the model.
    Note: If you create a frequency target or frequency constraint in the optimization, a frequency step is added to your analysis before performing the validation.

When the validation is complete, Functional Generative Design displays a contour plot of the results. You can review the results to estimate the values used to configure the optimization. For example, you can view a contour plot of stress and investigate regions of high stress. You can then create a constraint that limits the peak stress in the optimized model.
