Running a PowerFLOW Simulation

You can configure submission options and run a PowerFLOW simulation on the cloud.

This task shows you how to:

Before you begin: Create a case using PowerCASE.

Configure the Simulation

  1. Using the Connector for PowerFLOW, open PowerCASE.
  2. From PowerCASE, open the case and save it to the 3DEXPERIENCE platform.

    When you save a case, it creates a simulation object and an analysis case. You can create multiple analysis cases for the same simulation object (for example, coarse and fine cases). For more information, see the PowerCASE User's Guide.

  3. In PowerCASE, check and prepare the case.

    PowerCASE automatically saves the CDI file to the 3DEXPERIENCE platform because it is associated with an analysis case.

  4. From a 3DDashboard, open Simulation Manager.
  5. From the simulations panel, select an analysis case.
    The Content tab in the simulation details panel lists all the input files.
  6. From the simulation details panel, open the Setup tab.
  7. Select Discretization to discretize the CDI file.
  8. Select Simulation to simulate the CDI file.
  9. Under Simulation, you can select options to reduce the simulation time:
    OptionDescription
    Skip MME checkpoint at end. Reduces turnaround time by not creating an MME checkpoint at the end of the simulation.
    Skip full checkpoint at end Reduces turnaround time by not creating a full checkpoint at the end of the simulation.
    Seed from previous run Seeds the simulation from a previous run. If you select this option, information from the previous run appears in the configuration options.
  10. Select Postprocessing to set up a postprocessing job using an interactive session of PowerINSIGHT.

    For detailed information about this step, see Postprocessing PowerFLOW Results.

Run the Simulation

  1. From the toolbar in the details panel or the simulations panel, click Run.
    The run configuration options appear.
  2. Select one of the following License options:
    OptionDescription
    Tokens Licensing items that are checked out from the license pool to run the simulation and then returned when it is complete.
    Credits One-time consumable licensing items.

    Only simulation jobs consume token or credits. The dialog box shows an estimate of how many tokens or credits the job will consume. After the simulation is complete, the License Usage column on the Summary tab shows how many were consumed. For more information about tokens and credits, see Simulation Licensing.

  3. Specify the amount of memory allocated for the Discretization job.
  4. Specify the number of cores allocated for the Simulation job.
  5. Click Run.
    Simulation Manager submits a simulation job to run on the Cloud.
  6. As the simulation runs, the Content tab lists all the generated files (such as the .o, measurement, and watcher files). You can check these files while the job is running and when it completes.
  7. Open the Logs tab to view the log files. Use the list to select which log file to open:
    • Decomposer
    • Simulator Log
    • Discretizer Watcher
    • Discretizer Log
    • Simulator Watcher
    • PowerINSIGHT Log

When the simulation is complete, the next step is to visualize the results.
