Among these disciplines - mechanical structures, heat transfer, chemical engineering (including taking into account the chemical kinetics), electrical engineering, acoustics, geophysics and related phenomena on a micro-optic and high-frequency effects. For the analysis within a particular discipline is a specialized module, and to calculate the related problems among all the modules is carried out effective cooperation. A unique feature of COMSOL Multiphysics is its ability to use the opportunity MATLAB. COMSOL Multiphysics provides an efficient exchange of data with popular products of geometric modeling (Autodesk, Inventor, SolidWorks, CATIA, Pro / E, NX, SolidEdge, etc.
COMSOL Multiphysics - modeling package, which solves the system of nonlinear differential equations in partial derivatives of the finite element method in one, two and three dimensions. It can meet the challenges of the field of electromagnetism, elasticity, fluid dynamics and gas dynamics. COMSOL also provides an opportunity to solve the problem as a mathematical formulation (in the form of equations) and physical (the choice of physical models, eg models of the diffusion process). Certainly, in any case will be solved system of equations, and the difference lies only in the possibility of using the physical system of units and physical terminology. The so-called physical mode, you can also use pre-defined equations for the majority of the phenomena taking place in science and technology, such as the transfer of heat and electricity, the theory of elasticity, diffusion, wave propagation and fluid flow.
Framework for modeling is greatly enhanced with a software module COMSOL Script, which, although usually integrated with COMSOL Multiphysics (included in standard delivery), but can also operate as a standalone package. COMSOL Script - a language interpreter, which includes more than 600 commands for numeric computations and visualization in the command line mode. It allows you to create different scripts (procedures, written in text format). Save the template, made in COMSOL Script, can be a special model file (M-file), the interface can be used from COMSOL Script. With scripting, users can perform interactive parametric studies and optimization, as well as modeling. Thus, the graphics capabilities of the program COMSOL Script set new standards for packages in this category, and special tools allow you to quickly create graphical user interfaces.
The COMSOL Multiphysics simulation environment facilitates all steps in the modeling process - defining your geometry, meshing, specifying your physics, solving, and then visualizing your results.
Model set-up is quick, thanks to a number of predefined physics interfaces for applications ranging from fluid flow and heat transfer to structural mechanics and electromagnetic analyses. Material properties, source terms and boundary conditions can all be arbitrary functions of the dependent variables. Predefined multiphysics-application templates solve many common problem types. You also have the option of choosing different physics and defining the interdependencies yourself. Or you can specify your own partial differential equations (PDEs) and link them with other equations and physics. COMSOL Multiphysics operates as the primary tool for all your future modeling needs.
