EM.Tempo's default default mesh generator produces an adaptive brick mesh of your physical 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.

Occasionally, you may opt for a more regularized FDTD mesh with almost equal grid line spacings everywhere, but still with a frequency-dependent cell size. For that purpose, EM.Tempo offers the '''Regular''' FDTD mesh generator, which is a simplified version of its adaptive mesh generator. The regular FDTD mesh enforces only two criteria: '''Minimum Mesh Density''' and '''Absolute Minimum Grid Spacing'''. The grid cell sizes in this mesh are almost I=uniform in objects of the same material composition or in free-space regions.
Â
{{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.}}
