[2] FEATool Multiphysics features the ability to model fully coupled heat transfer, fluid dynamics, chemical engineering, structural mechanics, fluid-structure interaction (FSI), electromagnetics, as well as user-defined and custom PDE problems in 1D, 2D (axisymmetry), or 3D, all within a graphical user interface (GUI) or optionally as script files.

[8] FEATool Multiphysics is a fully integrated physics and PDE simulation environment where the modeling process is subdivided into six steps; preprocessing (CAD and geometry modeling), mesh and grid generation, physics and PDE specification, boundary condition specification, solution, and postprocessing and visualization.

Using the SU2 and OpenFOAM GUI[11] interfaces automatically converts fluid dynamics models to compatible corresponding mesh, boundary, and control dictionary files, runs simulations, and afterwards imports and interpolates the resulting solutions back into the toolbox.

GUI operation is recorded as equivalent function calls, and therefore in addition to binary formats, FEATool simulation models can also be saved and exported as fully scriptable and editable MATLAB compatible m-script files.

[17] Similar to the external solver interfaces, FEATool features built-in support for the Gmsh[18] and Triangle[19] mesh generators.
