SEMCAD-X
SEMCAD X SOLUTIONS
SEMCAD X is the latest generation of 3-D FDTD & FIT full-wave simulation software offering unprecedented levels of user-friendliness, speed & memory efficiency. Its application range has been greatly extended by, e.g., effective GA optimization of parametrized CAD derived structures and superior speed (>50x faster than others). Unique enhancements to the GUI, including the ACIS® CAD modeler and the ultra-fast OGL renderer allow the analysis and design of real-world configurations without any compromise.
