Running a Parametric Optimization

You can use parametric optimization to perform detailed refinement of selected regions of your model.

Before you begin:
  • Make sure you have the Detailed Refinement Designer role (DOF).
  • You must have a simulation object with a meshed part, loads and boundary conditions, and results.
  • Make sure that the context is specified to Scenario .

  1. From the Design Study section of the action bar, select Parametric Optimization .
  2. In the Objectives pane:
    1. Select the parameter representing the objective of the optimization.

      You can only create a single objective.

    2. Select whether the optimization must minimize or maximize the objective.
  3. In the Design Parameters pane:
    1. Select the design parameters that will vary during the optimization.
    2. Enter the lower and upper bound of each design parameter.
  4. In the Constraints pane:
    1. Select constraints on the solutions considered by the optimization.
    2. Enter the lower and upper bound of each constraint.
  5. In the Execution Options pane, choose the options described in the following steps.
  6. Choose the Location where the optimization (simulation) is run.
    OptionDescription
    Local Runs the simulation on the private 3DOrchestrate Station on your computer.
    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 will run; see About Remote Simulate Options for 3DOrchestrate.
  7. 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.

  8. 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.

  9. Optional: Adjust the Maximum number of cycles.

    The optimization continues until it has converged or until the specified number of design cycles (iterations) has been reached.

  10. Enter the maximum time limit for the optimization.

    By default, there is no time limit, and the optimization continues until the specified number of iterations (design cycles) has been reached. Specifying a time limit allows you to obtain the best possible geometry within the given time.
