* Fixed-Cell Mesh
EM.Tempo's default default mesh generator produces an adaptive brick mesh of your physical structure. EM.Tempo also offers a uniform, whose mesh resolution varies with the frequency-independent. As the operating frequency of your project increases, fixed-cell the default '''Adaptive''' FDTD mesh generatorcreates a larger number of smaller voxels for a given physical structure. The fixed-cell adaptive mesh consists of three uniform grids along is optimized in such a way as to capture all the XYgeometric details, YZ curvatures and ZX principal planesthin slanted plates or sheets, which often pose a challenge to staircase meshing. It usually provides a reasonably accurate dirscretization of most complex structures. 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. In that case, the fixed-cell you can use EM.Tempo's '''Regular''' FDTD mesh generator tries to fit your physical structure to the , which is indeed 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 rather than adapting the cell sizes in this mesh to your physical structureare almost uniform in objects of the same material composition or in free-space regions.

{{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.}}
