Multiphysics Modeling of Heat Induced Stress in a Brake Disk

Matlab Modeling and FEM Simulation of Heat Induced Stress

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 …

MATLAB CFD Solver Benchmark - OpenFOAM and FEATool Multiphysics

To evaluate the efficiency of the OpenFOAM CFD solver one can use the now classic DFG flow over a cylinder CFD benchmark [1] for which very accurate reference solutions for drag, lift, and pressure difference have been established [2]. The model problem is set up and solved with identical grids and finite element FEM …

Matlab Modeling and FEM Simulation of Axisymmetric Stress-Strain

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 …
