FEATool is a fully integrated simulation environment, which has been tested and verified to work with 64-bit Windows, Linux, and MacOS operating systems with a minimum of 4 GB RAM memory.

In order to use FEATool, the software must first be installed on the intended computer system. It is recommended to first uninstall previous versions before installing/upgrading to a newer version.

Please follow the steps below to install FEATool as a stand-alone app, or as a MATLAB® toolbox. The installers can be downloaded directly from the FEATool releases and installed manually, or installed from the MATLAB® APPS and Add-On Toolbar as a toolbox.

Use the steps below to install the app in stand-alone mode

1. First download the installer for your operating system

   • FEATool Windows Installer

   • FEATool Linux Installer

2. Save it to a directory and run the installer. This will first download and/or install the application runtime if required (which may require up to 10 GB space to install), and then the program file will be extracted.

3. When everything has been installed, run the program file to start FEATool. Please be patient as the application runtime can take some time to start.

Follow the steps below to install FEATool as a MATLAB® toolbox, and to enable running MATLAB® simulation m-scripts

1. Download the FEATool_Multiphysics.mlappinstall toolbox installation file.

2. Then start MATLAB®, press the APPS toolbar button, and select the Install App button.

3. When prompted to choose a toolbox file to install, select the FEATool_Multiphysics.mlappinstall file and press OK.

4. Press the Install button if prompted to "Install to My Apps".

Once the toolbox has been installed, an app icon will be available in the APPS toolbar to start the FEATool GUI. (Note that MATLAB® may not show or give any indication of the toolbox installation progress or completion.)

Automated modeling tutorials and examples for various multi-physics applications can be selected and run from the File > Model Examples and Tutorials menu option in the GUI.

Example script files and simulation models are also available in the examples folder of the FEATool program directory. Moreover, new tutorials and articles are frequently published on the FEATool blog & technical articles.

FEATool and the GUI has been specifically designed to be as easy to use as possible, and making learning multiphysics simulation by experimentation easy.

The standard modeling process is divided into six different steps or modes

• Geometry - Definition of the geometry to be modeled
• Grid - Subdivision of the geometry into smaller grid cells suitable for computation
• Equation - Specification of physics, material parameters, and coefficients
• Boundary - Boundary conditions specify how the model interacts with the surrounding environment (outside of the geometry)
• Solve - Solution and simulation of the defined model problem
• Post - Visualization and postprocessing of simulation results

These modes can be accessed by clicking on the corresponding buttons in left hand side Mode toolbar. Each mode has specialized and different Tools available in the toolbar that will be activated when selected. Additional and advanced mode options are also be available in the mode menus.

Basic use and how to set up and model coupled fluid flow and temperature in a heat exchanger is explained in the linked video tutorial (click on the image below to start the tutorial).

The FEATool Documentation is available online, and also by selecting the corresponding option in the Help menu of the GUI.
