Finite Element Method (FEM)

The finite element method (FEM) is a numerical procedure for solving partial differential equations. FEM is popular in branches like mechanical and plant engineering, vehicle manufacturing (automotive), aviation and aerospace engineering and medical technology.

FEM is frequently applied to calculations and simulations for  deformations and stresses in components and modules. It is also ideal for solving heat transfer problems. Physical input variables for calculation are known as initial conditions and boundary conditions. Depending on the selected calculation methods or the underlying equation these can be forces, pressures, heat flow, electrical current as well as electrical charges and magnetic flow.

At ITB GmbH fluid-structure-interaction (FSI) is especially important. We use results from CFD simulations as physical input variables for an FE/calculation. We then calculate a mechanical or thermal induced deformation and if applicable the heat dispersion in components. Through back coupling the deformation can influence current flow.

Our calculation engineers are delighted to support you with defining physical input variables, preparing high quality computation grids as well as selecting and implementing calculations methods (mechanical, thermal, linear, non-linear etc.)
