FEATool Multiphysics

FEATool Multiphysics is a fully integrated physics modeling and engineering simulation environment, featuring built-in CAD and geometry tools, pre-processing and grid generation, solvers, post-processing and visualization.

Predefined physics modes are available which easily can be combined to set up of different multi-physics simulation problems including fluid flow (computational fluid dynamics CFD), heat transfer, structural stresses, electrostatics, reaction and transport of mass and chemical species. Moreover, users can also specify their own custom equations and physics modes.

FEATool is completely written in Octave and Matlab m-script source code, and is fully documented with over 50 model examples and tutorials. Moreover, the Matlab FEM function library is fully documented, open, and designed to be easy to use. This approach makes FEATool extensible, adaptable, and customizable to each users needs.

Toolbox Features

• Geometry modeling in 1D, 2D, and 3D.
• Automatic unstructured grid generation on complex geometries with triangular and tetrahedral cells.
• Linear, triangular/tetrahedral, and quadrilateral/hexahedral cells with several constant, 1st-5th order conforming and non-conforming FEM basis functions.
• Stationary and time-dependent linear and non-linear solvers.
• Built-in postprocessing and visualization including boundary and subdomain integration, and also sharing data on-line with Plotly.
• Support for external solvers, grid generation (with for example Triangle) and postprocessing tools directly callable from the GUI.
