[[EM.Tempo]] generates a brick volume mesh for FDTD simulation. The FDTD mesh is a rectangular Yee mesh that extends to the entire computational domain. It is primarily constructed from three mesh grid profiles along the XY, YZ and ZX principal planes. These projections together create a 3D mesh space consisting of a large number of cubic cells (voxels) carefully assembled in a way that approximates the shape of the original structure.

EM.Tempo also offers a uniform, frequency-independent, fixed-cell FDTD mesh generator. The fixed-cell mesh consists of three uniform grids along the XY, YZ and ZX principal planes. In that case, the fixed-cell mesh generator tries to fit your physical structure to the mesh grid rather than adapting the mesh to your physical structure.
