{{Note|When choosing a mesh type for your FDTD simulation, keep in mind that adaptive and regular mesh types are frequency-dependent and their density varies with the highest frequency of your specified bandwidth, while the uniform mesh type is always fixed and independent of your project's frequency settings.}}

===Viewing the FDTD Mesh===
Â
To generate an FDTD mesh and view it the project workspace, follow these steps:
Â
* First, click the '''Mesh Settings''' [[Image:mesh_settings.png]] button of the '''Simulate Toolbar''' or select '''Menu > Simulate > Discretization > Mesh Settings...''', or right click on the '''Yee Mesh''' item of the Navigation Tree and select '''Mesh Settings...''' from the contextual menu, or use the keyboard shortcut '''Ctrl+G'''. The Mesh Settings Dialog opens up, where you can set the values of the various mesh [[parameters]] including the '''Mesh Density'''.
* After specifying the desired mesh density, you can examine the mesh grid plane. The XY, YZ, and ZX mesh grid planes can be displayed through '''Menu > Simulate > Discretization > Grid Planes > XY Plane''', '''YZ Plane''' or '''ZX Plane''' or by right clicking on one of the three '''XY Plane''', '''YZ Plane''' or '''ZX Plane''' items in the '''Discretization''' section of the Navigation Tree and selecting '''Show''' from the contextual menu. The mesh grid planes give you a good idea of what the mesh will look like once it is generated and its resolution along different planes. To remove a mesh grid plane from the project workspace, select '''Menu > Simulate > Discretization > Grid Planes >''' one more time and remove the check mark in front of the name of the currently displayed mesh grid plane, or right click on the name of the currently displayed mesh grid plane in the Navigation Tree and select '''Hide''' from the contextual menu.
* To display the FDTD mesh, click the '''Show Mesh''' [[Image:mesh_tool.png]] button of the '''Simulate''' '''Toolbar '''or select '''Menu > Simulate > Discretization > Show Mesh''' or use the keyboard shortcut '''Ctrl+M'''. This takes [[EM.Cube]] into its "Mesh View" mode, and the Yee mesh of the whole structure is displayed in the project workspace. While the mesh view is enabled, the '''Show Mesh''' [[Image:mesh_tool.png]] button remains depressed. To get back to [[EM.Cube]]'s "Normal View" mode, click this button one more time, or deselect '''Menu > Simulate > Discretization > Show Mesh''' to remove its check mark or simply hit the '''Esc Key''' of the keyboard.
