COMSOL Multiphysics a

119 COMSOL Multiphysics v3.5a COMSOL Multiphysics is a simulation package that solves systems of nonlinear partial differential equations using finite element methods in one, two, and three dimensions. It allows you to solve problems in the field of electromagnetism, elasticity theory, dynamics of liquids and gases, and chemical gas dynamics. COMSOL Multiphysics also makes it possible to solve the problem both in a mathematical formulation (in the form of a system of equations) and in a physical one (choosing a physical model, for example, a model of the diffusion process). Of course, in any case, a system of equations will be solved, and the difference lies only in the ability to use physical systems of units and physical terminology. In the so-called physical mode of operation, it is also possible to use predefined equations for most phenomena occurring in science and technology, such
