ANSYS - the universal program system for the finite element method (FEM) analysis, the existing and evolving over the past 30 years, is quite popular among the specialists in the field of computer engineering (CAE, Computer-Aided Engineering) and CE solutions of linear and nonlinear, stationary and unsteady three-dimensional problems of solid mechanics and mechanics of structures, including non-stationary geometrically and physically nonlinear problems of contact interaction of structural elements, tasks, gas and fluid mechanics, heat transfer and heat transfer, electrodynamics, acoustics, and mechanics-related fields. Modeling and analysis in some areas of the industry to avoid costly and lengthy development cycles such as "design - manufacture - test". The system operates on the basis of the geometric kernel Parasolid.
