XFdtd® is a full-featured EM simulation solver that simplifies the analysis of even the most complex and massive problems. XF outpaces other methods in efficiency as the number of unknowns increases and includes full-wave, static, bio-thermal, optimization, and circuit solvers to tackle a wide variety of applications. XF also works with Remcom's ray-tracing products to provide thorough simulation capability at the low-, middle-, and high-end of the electromagnetic spectrum.
