Toolbox Download and Installation

The FEATool Multiphysics Toolbox can be installed directly from the MATLAB APPS and Add-On Toolbar, the MathWorks File Exchange, or downloaded directly from the link below

FEATool Multiphysics Download


The FEATool Multiphysics simulation toolbox is written in the m-script language, which requires MATLAB to run and interpret the source code. MATLAB is available from The Mathworks Inc.

FEATool has been verified work with Windows, Mac, and Linux operating systems running MATLAB versions 7.9 (R2009b) and later. Furthermore, a system with 4 GB or more RAM memory is recommended. To install, first download and extract the FEATool distribution and software archive.


In order to use the FEATool Multiphysics, toolbox the included files and directories must be installed on the intended computer system. It is recommended to first uninstall older versions of FEATool before updating to a newer version.

  • For MATLAB 2012b and later double click on the FEATool Multiphysics.mlappinstall file, or use the Get More Apps button in the MATLAB APPS toolbar. Once the app has been installed, a corresponding icon will be available in the toolbar to start FEATool. (Note that MATLAB may not show or give any indication of the app installation progress or completion.)

FEATool Multiphysics Toolbox available as MATLAB Add-On

  • For MATLAB 2009b-2012a, use the addpath command to add the extracted featool program directory to the MATLAB search paths, so that the program files can be found by the interpreter (for example addpath C:\featool). Then enter the command featool at the MATLAB command prompt to start the toolbox GUI and application.

Please note, that using spaces in user and installation directory paths is not recommended as it may cause issues with the external grid generation and solver interfaces. Moreover, as all functions are initially loaded into memory, FEATool may take some time to load and show the GUI on initial startup.


To get started with FEATool you can try out some of the built-in tutorials which can be run directly from the File > Model Examples and Tutorials menu option in the FEATool GUI, or example models and video tutorials.
