A universal software system for finite element (FEM) analysis that has existed and developed over the past 30 years is quite popular among specialists in the field of computer-aided engineering calculations (CAE, Computer-Aided Engineering) and FE solutions of linear and nonlinear, stationary and non-stationary spatial problems of deformable solid mechanics and structural mechanics (including non-stationary geometrically and physically nonlinear problems of contact interaction of structural elements), problems of fluid and gas mechanics, heat transfer and heat transfer, electrodynamics, acoustics, as well as the mechanics of coupled fields.
