To view the mesh, click the <b>Show/Generate Mesh</b> button of the Simulate Toolbar (or alternatively use the keyboard shortcut <b>Ctrl+M</b>). For this particular project, the mesh view does not reveal much because the mesh of a vertical line object conforms to the grid. In general, the mesh view shows how the simulation engine sees your physical structure. You can also display the three mesh grid planes by right clicking on one of the three items XY Grid Plane, YZ Grid Plane, or ZX Grid Plane in the “Discretization” section of the Navigation Tree and selecting <b>Show</b> from the contextual menu. To remove the grid planes from the project workspace, open the same contextual menu and select <b>Hide</b>.
