Coupled Multiphysics Modeling of Resistive Heating in a Tungsten Filament
Coupled Multiphysics Modeling of Resistive Heating in a Tungsten Filament
The following tutorial discusses multiphysics modeling of resistive Joule heating simulated with the FEATool Multiphysics MATLAB FEM toolbox. In the model the resulting current from an applied electric potential will heat a thin spiral shaped Tungsten wire, such as can be found in incandescent light bulbs. After the …
Multiphysics Modeling of Heat Induced Stress in a Brake Disk
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 …
Adding Multiphysics Equations and Using Complex Expressions
Adding Multiphysics Equations and Using Complex Expressions
The FEATool GUI makes it easy to add and coupled multiphysics equations and complex expressions to your models. This post illustrates how to do this. After starting to work with a physics mode it is easy to add one or more other modes by going to the + tab in the Equation Settings dialog box. There you can simply …
