Generating the Volume Mesh

The first step in generating a volume mesh is to create a fluid region from the imported geometry part.

Use the following steps:
  1. Right-click the Geometry > Parts > GrainSystem node, and select Assign Parts to Regions...
  2. In the Assign Parts to Regions dialog, make sure that the GrainSystem part is selected, and set the second dropdown to Create a Boundary for Each Part Surface.

  3. Click Apply, and then Close.
To create a meshing continuum with a base size of 0.1 m:
  1. Right-click Geometry > Operations and select New > Mesh > Automated Mesh.
  2. In the Create Automated Mesh Operation dialog:
    1. In the Parts list, select GrainSystem
    2. In the Select Meshers box, select the following meshers:
      Group Mesher
      Surface Meshers Surface Remesher
      Core Volume Meshers Polyhedral Mesher
  3. Select the Automated Mesh > Default Controls > Base Size node and set Value to 0.1 m.
  4. Click (Generate Volume Mesh) in the Mesh toolbar.
    The output from the meshers is shown in the Output window. When the meshing process is complete, the message Volume Meshing Pipeline Completed is displayed in the Output window.
  5. Select Scenes > Geometry Scene 1 > Surface 1 and activate Mesh.
  6. Select Scenes > Geometry Scene 1 > Displayers > Geometry 1 and activate Mesh.
  7. In the Geometry Scene, right-click and select Apply Representation to Displayers > Volume Mesh to see the result.

  8. Save the simulation.
