PrOGrid Project Optimized Gridding®
PrOGrid Project Optimized Gridding simplifies grid creation.
The algorithm refines the grid around the discontinuities in the copper trace.
PrOGrid incorporates best practices in FDTD modeling by considering multiple aspects of a project to optimize the grid for both accuracy and runtime. Users have the ability to control the following aspects of gridding:
Finer resolution around conductor edges where fields are strongest
Minimum number of cells across features, e.g. microstrips and substrates
Smaller cells inside dielectrics where the wavelength is shorter
Free space padding that is determined based on a fraction of a wavelength
