To enable this option in the context menu, click the Show More Options button () and select Multigrid Level in the Show More Options dialog box. Then right-click any of the Study Step nodes to add a Multigrid Level () node, which specifies the geometric multigrid level used by the study.

Select a Physics interface. In the Discretization list, you can specify which discretization to use (defined in the main physics interface’s Settings window or in any added Discretization node; see Discretization (Node)). Changing the discretization can affect the discretization order used by this study. You have to add the discretization you want to use in the physics interface.

Select a mesh to use for each geometry in the study. First select the Geometry from the list and then select the Mesh from the list.
