Loading the Starting Simulation File

You are provided with a starting simulation file that contains the battery module geometry, pre-defined mesh operations, regions, interfaces, generated reports, monitors and plots. The file also includes two tables, Heat Rate and Vent Rate, which define the heating rate for the Thermal Runaway Heat Release and Thermal Runaway Battery Vent models.

Due to the large number of cells and the time it takes the solver to run, you are advised to launch this tutorial in parallel on at least 4 cores to reduce the meshing and run time.
To load the starting simulation file:
  1. Start up Simcenter STAR-CCM+ in a manner that is appropriate to your working environment and select File > Load....
  2. In the Load a File dialog:
    1. Select an appropriate parallel option and set Compute Processes to at least 4.
    2. Click Browse
    3. In the Open dialog, navigate to the battery folder of the downloaded tutorial files and select thermalRunaway_start.sim.
    4. Click Open, then OK.
  3. To visualize the imported geometry, create a new Geometry scene.
  4. Click (Make Scene Transparent).


  5. To generate the volume mesh, right-click the Geometry > Operations node and select Execute All.
  6. To view the volume mesh, create a new mesh scene.
  7. Click (Make Scene Transparent).


  8. Save the simulation as thermalRunaway.sim.
