Siemens NX
NX, formerly known as "Unigraphics", is CAD/CAM/CAE software, which has been owned since 2007 by Siemens Digital Industries Software. In 2000, Unigraphics purchased SDRC I-DEAS and began an effort to integrate aspects of both software packages into a single product which became Unigraphics NX or NX. It is used, among other tasks, for: Design (parametric and direct solid/surface modelling) Engineering analysis (static; dynamic; electro-magnetic; thermal, using the finite element method; and fluid, using the finite volume method).
