To mesh a model

Use the Generate Mesh icon to generate a mesh.

1. In the Layers pane, select the model regions that you want meshed.
   Note: Only the model layers visible in the Layers pane are meshed.
2. Click (Mesh tab > Mesh panel > Generate Mesh)
3. As necessary, select the General, Curves, CAD, NURBS, Tetra¹ or Tetra Advanced tab, depending on the type of mesh you are generating, and make changes to the meshing parameters.
   Note: Use the 3D Mesher option from the Tetra tab to choose between the Legacy mesher or the Advancing Front mesher. The Advancing Front meshing technique allows you to set the Maximum allowed edge length through thickness as well as the Maximum allowed aspect ratio.
   Tip:

   • Click Save Default Values to save all the parameters marked with a * as the default value.
   • Click Use Default Values to reset all the parameters marked with a * to the current default option.
4. Click Mesh Now to mesh the model.

Accept the default Global edge length on surface as an initial estimate. If this edge length is too coarse decrease it to 1/3 to 1/2 of the initial value. Alternatively, set the Global edge length on surface to about 2 times the nominal wall thickness for a 3D mesh, and 2 - 5 times the nominal wall thickness for a Dual Domain mesh.

Note: The Job Manager manages mesh generation.
