Configuring the Heart Model

You must configure the Heart Model and save the modified simulation process.

The Heart Model simulation process captures most of the configuration steps that are required to execute the process. For example, the simulation process always runs the electrical analysis step before the mechanical analysis step and specifies that the mechanical analysis will run in double precision to ensure sufficient accuracy.

However, before you execute the simulation process containing the Heart Model, you must perform the steps below.

  1. Open the tab containing the simulation process in the Process Composer app.
  2. Select the Run Living Heart Simulation activity.
  3. From the context toolbar that appears, select Parameters .
  4. In the Parameters dialog box that appears, do the following:
    1. Enter the number of CPUs (numCPUs) that will be used to analyze the Heart Model. To improve computational efficiency, it is recommended that you use 16 or more CPUs to run the simulation. Using fewer CPUs may result in significantly longer computational times.
    2. If desired, change the path to the Python script that is used to modify the Abaqus input file (pathToModificationScript). The default path is imported from the 3DXML file containing the Heart Model; and, in most cases, you do not need to change the default value.
    3. Click Close to save your changes and to close the Parameters dialog box.
  5. Right-click the Run Living Heart Simulation activity, and select Activity Options from the menu that appears.
  6. From the Affinities tab, click and select the 3DOrchestrate Station that will execute the simulation process. You must select a station running on a Windows machine.
    See “Configuring the Affinities” in the Process Composer Guide for more information.
  7. Click Ok to close the Activity Options dialog box.
  8. From the top bar, select Share > Save and save your modified simulation process.
