Solving a Region with FEM

To solve a model with the finite element method (FEM), you must activate FEM for each relevant region.

  1. Select the region (or regions) in the in the 3D view or in the details tree that you want to solve with the FEM.
  2. In the details tree, from the right-click context menu, select Properties.
  3. On the Region properties dialog, click the Solution tab.
  4. Under Solution method, from the drop-down list, select Finite Element Method (FEM).
  5. Under Element order control, select the Local element order control check box to specify the element order locally per region.

    This setting takes preference over the element order set per model. Use First order only (reduced accuracy) to reduce the required memory, run-time and accuracy.

    Note: Use First order only only if the mesh is already very fine to account for highly inhomogeneous media or very complex geometry.
  6. Click OK to save the region properties and to close the dialog.
