Importing the Volume Mesh

To set up the Simcenter STAR-CCM+ simulation, launch a simulation and import the supplied volume mesh.

Launch Simcenter STAR-CCM+.
Start a simulation.
Import the manifoldGT-SUITE.ccm volume mesh from your working directory.

Note When creating this volume mesh, the Extruder was used to generate orthogonal cells in each averaging zone. This mesh helps to capture the one-dimensional nature of the flow in these zones.

Simcenter STAR-CCM+ provides feedback on the import process in the Output window and a mesh region is created under the Regions node.

Display the imported volume mesh and store a convenient view:

Create a mesh scene.
Click (Save-Restore-Select views) and select Views > -X+Y-Z > Up +Y.
Click (Save-Restore-Select views) and select Store Current View, which saves this view for later use.
Save the simulation as manifold-gt.sim.
