FEATool Multiphysics - Matlab FEM Toolbox

Matlab Finite Element Analysis FEM Multiphysics Toolbox

FEATool Multiphysics is an GNU Octave and Matlab FEM and PDE toolbox for modeling and simulation of physics, continuum mechanics, and engineering applications with the finite element method.

With an easy to use GUI and full suite of functions and subroutines for geometry preprocessing (CAD), grid and mesh generation, solvers, postprocessing and visualization, FEATool is a fully integrated, complete, and self contained FEM toolbox.


Intuitive and Easy to Use GUI

FEATool features an easy to use graphical user interface (GUI) allowing full access to functionality such as geometry and CAD tools, grid generation, defining equations and multiphysics couplings, FEM assembly and solvers, as well as postprocessing.

Moreover, FEATool FEM models can be saved and exported as both compact binary data, and also Matlab m-script text file formats, the latter allowing for a fast and easy approach to learn the FEM function syntax and interfacing with other Matlab toolboxes and functions.

Easy to Use Matlab GUI for FEM Simulations
Matlab Multiphysics Equations and FEM Physics Modes

Predefined Multiphysics Modes

15 predefined physics modes are available which easily can be combined to set up of complex coupled multiphysics simulation problems including fluid dynamics (CFD), heat transfer, structural mechanics (SME), electromagnetics, and convective, diffusive, and reaction transport of mass and chemical species. Moreover, in FEATool editing and entering general expressions, custom equations, and PDEs is easy with the simple PDE formulation syntax.


Customizable and Extensible

FEATool is entirely written in fully documented Octave and Matlab m-script source code, and is designed to be very easy to understand and learn. Moreover, the open approach makes the code base extensible, adaptable, and customizable to each users needs, with functionality to write Matlab m-script user defined functions, and interface with external simulation and software tools such asFeatFlowFEniCS, and Plotly.
