Refining the Volume Mesh

Continuing from the cylinder.sim file, you now create a cylindrical part, 0.02 m in radius, which defines the outer extent of the region to be refined.

  1. Click the Geometry Scene 1 tab in the graphics window.
  2. Right-click the Geometry > Parts node and select New Shape Part > Cylinder.
  3. In the Create/Edit Cylinder Part panel, set the following values:
    Property Setting
    Start Coordinate [0, 0, 0] m
    End Coordinate [0, 0, 0.041] m
    Cylinder Radius [0.02] m
  4. Cllick Create and Close.
  5. Select the Geometry > Parts > Cylinder node, to display the cylinder part that you created in Geometry Scene 1.

You now create a volumetric control and select the shape that defines the source.

  1. Expand the Geometry > Operations > Automated Mesh node.
  2. Right-click the Custom Controls node and select New > Volumetric Control.
    A new node, Volumetric Control 2, is created in the simulation tree.
  3. Select the Volumetric Control 2 node and set Parts to Cylinder.
  4. Expand the Volumetric Controls 2 > Controls node and select Trimmer.
  5. In the Properties window, enable Customize isotropic size.
    A new node,Values, is added to the simulation tree.
  6. Select the Volumetric Controls 2 > Values > Custom Size node and set Size Type to Absolute.
  7. Set the Value to 8.0E-4 m.
  8. Click (Generate Volume Mesh) in the Mesh Generation toolbar.

The output from the meshers is shown in the Output window and the ongoing status is shown in the status bar. The solution obtained on the coarse mesh is interpolated onto the new mesh.

  1. Save the simulation.
