COMSOL Multiphysics Engineering Simulation Software

finite element analysis of a turbine stator blade
Thermal Stress: A stator blade in the turbine stage of a jet engine is heated by combustion gases, where the resulting temperature gradients introduce significant stresses. To prevent the stator from melting, air is passed through a cooling duct in the blade. Shown is the temperature distribution throughout the blade and in the flow stream.

COMSOL Multiphysics®

The COMSOL Multiphysics simulation environment facilitates all the steps in the modeling process – defining your geometry, meshing, specifying your physics, solving, and then visualizing your results. It also serves as a platform for the application specific modules.

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 electrostatics. Material properties, source terms, and boundary conditions can all be spatially varying, time-dependent, or functions of the dependent variables. You can freely mix physics interfaces into new multiphysics combinations as well as couple with any application specific module.

As an alternative to writing your own simulation code, the COMSOL Multiphysics user interface gives you the option to specify your own partial or ordinary differential equations (PDEs or ODEs) and link them with other physics interfaces. When combined with the CAD Import Module or one of the LiveLink products, this enables you to run custom simulations on CAD models from industry-standard formats.
