A program for finite element calculations of complex scientific and technical problems. The COMSOL Multiphysics package allows you to simulate almost all physical processes that are described by partial differential equations. The program contains a variety of solvers that will help you quickly solve even the most complex problems, and the simple structure of the application ensures ease and flexibility of use. The solution of any problem is based on the numerical solution of equations in partial derivatives by the finite element method. The range of tasks that can be modeled in the program is extremely wide.
