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 engineering simulation software 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.
