Multiphysics Modeling of Heat Induced Stress in a Brake Disk
This tutorial illustrates how to couple a heat transfer model with linear elasticity by manually defining the multiphysics equations with the FEATool PDE syntax. The custom model examines how temperature rise in a brake disk under braking results in heat induced displacements with resulting increased stresses and …

Axisymmetric Stress-Strain Script Modeling
Continuing on the previous post on axisymmetric modeling in FEATool, we will here take a look at how to model axisymmetric stress-strain from structural mechanics by entering and parsing the governing equations directly into FEATool using MATLAB m-file scripting. The problem we will be looking at is a hollow sphere …
Fortran, Julia, and MATLAB FEM Benchmark Comparison
Continuing the previous Finite Element Method (FEM) solver and assembly benchmark comparison, this follow up compares the entire solution process for an identical simulation problem, in this case a two-dimensional (2D) Poisson problem solved on a unit square. The model problem is stationary, and discretized with …
Custom Equations and the Weak PDE Formulation Equation Syntax
The following post further examines PDE equation parsing and specifying custom equations in FEATool. Furthermore, a simple parametric heat transfer model will be shown and set up as a custom PDE equation, suitable for both the MATLAB command line and m-script file modeling. Stationary heat transfer by conduction and …
Different Ways of Working with FEATool and FEM Simulations
FEATool Multiphysics is unique in that it allows several different ways for users to work with FEM modeling and simulation. The whole spectrum from using the high-level graphical user interface down to low-level access of the fundamental matrices of the underlying finite element FEM discretization is possible. On top …
Implementing Custom and User Defined Finite Element Shape and Basis Functions
FEATool has been designed with flexibility and user customization in mind allowing for solving custom equations, calling external solvers, grid generators, and post processing tools, and allowing for both MATLAB m-script as well as GUI based modeling. This post shows how to easily define custom finite element shape …
Automatic Unstructured Quadrilateral Grid Generation
QuadMesh is a MATLAB cross compatible automatic and unstructured quadrilateral grid generation code, developed to be used with the FEATool Multiphysics MATLAB Finite Element simulation toolbox. Using quadrilateral grid cells are often advantageous to simplex or triangular cells in that they can provide somewhat more …
