In [[EM.Cube]]'s "Mesh View" mode, you can rotate or pan the view of the project workspace, but you cannot edit the objects. '''"Show Mesh"''' generates a new mesh and displays it if there is none in the memory, or it simply displays an existing mesh in the memory. This is a useful feature because generating an FDTD mesh may take a long time depending on the complexity of structure and the total size of the computational domain. If you change the structure or alter the mesh settings, a new mesh is always generated. You can ignore any mesh in the memory and force [[EM.Cube]] to generate a fresh FDTD mesh from the ground up by selecting '''Menu > Simulate >Discretization > Regenerate Mesh''' or by right clicking on the '''Yee Mesh''' item of the Navigation Tree and selecting '''Regenerate''' from the contextual menu.
