HFSS Transient Solver Option

The HFSS transient solver is a 3-D full-wave transient or time domain electromagnetic field solver based on the discontinuous Galerkin method (DGTD). This tetrahedral finite element technique exploits the same automatic adapted-for-accuracy meshing technology that made HFSS the gold standard for accuracy in electromagnetics. You can investigate, extract and visualize fields in applications with pulsed excitations, such as time domain reflectometry (TDR), ground-penetrating radar, electrostatic discharge, electromagnetic interference and lightning. This technology complements the frequency domain solution technology in HFSS by enabling you to understand the electromagnetic characteristics of your design in detail.
