FEATool Multiphysics™ – Physics Simulation Made Easy

About

FEATool Multiphysics
(short for Finite Element Analysis Toolbox), is a fully integrated
toolbox for modeling and simulation of coupled physics phenomena,
partial differential equations (PDE), continuum mechanics and
engineering problems.

FEATool Multiphysics aims to provide a truly easy to use and
comprehensive all-in-one integrated simulation platform for all
kinds of multi-physics analysis. By combining the best of intuitive
usability, extensibility, and customization features,
such as

Graphical User Interface (GUI)
Built-in geometry and CAD modeling tools
Automatic grid and mesh generation
Postprocessing and visualization
Fully programmable and scriptable

makes FEATool Multiphysics a suitable simulation and modeling tool
for everyone from students learning mathematical modeling, to
researchers and engineers wishing to explore new ideas in a simple,
fast, and convenient way.

simulation apps in custom applications and toolboxes)

System Requirements

The FEATool Multiphysics toolbox is a fully integrated simulation
environment for use with MATLAB®. FEATool has been tested and
verified to work with 64-bit Windows, Mac OSX, and Linux operating
systems running MATLAB versions 7.9 (R2009b) and later. Furthermore,
a system with a minimum of 4 GB RAM memory is recommended.

Installation

In order to use the FEATool Multiphysics toolbox it must first be
installed on the intended computer system. The toolbox can be
installed from the MATLAB® APPS and Add-On Toolbar, or downloaded
directly from the Precise Simulation GitHub repository
and installed manually.

Please follow the steps below for your matching system to install
FEATool as a MATLAB toolbox. It is recommended to first uninstall
previous versions of toolboxes before installing/upgrading to a
newer version. Also note that, as all functionality is loaded into
memory at startup, the toolbox may take some time to fully initialize
and launch the GUI.

MATLAB 2012b and later

First download the latest FEATool Multiphysics.mlappinstall
toolbox installation file (if you have downloaded a zip archive
instead, then extract the mlappinstall file from inside it).
Then start MATLAB, press the APPS toolbar button,
and select the Install App button.
When prompted to choose a toolbox file to install, select the
FEATool Multiphysics.mlappinstall file and press OK.
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.)

MATLAB 2009b-2012a

First download the latest FEATool Multiphysics zip archive
and extract it to a convenient folder on your system.
Start MATLAB in this folder, or change to the folder location in
the MATLAB CLI interpreter with the command
cd path_to_featool_program_folder
Run the command start_featool_gui from the FEATool program folder
to start the GUI.

For convenience, one can also use the addpath path_to_featool_program_folder
command to permanently add the FEATool program folder to the MATLAB
search paths (one can then start FEATool from any location).

Tutorials and Examples

Pre-defined 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 periodically published on the FEATool Technical Articles Blog

Basic Use

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

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 usage and how to set up and model fluid flow past an obstacle
is explained in the linked video tutorial
