(PDE). In the following it is shown how the custom equation feature
can be …

## Custom Implementation of an Algebraic Turbulence Model

## Custom Implementation of an Algebraic Turbulence Model

Performing accurate simulation of turbulent flows is still a challenging topic today, especially with limited computational resources. Although the Navier-Stokes equations are perfectly valid in the turbulent flow regime, one typically have to resort to some form of turbulence modeling in order to reduce computational …

## Euler-Bernoulli Beam - FEATool Modeling and Implementation Example

This post will discuss how to implement and model elastic deformations of simple beams with FEATool Multiphysics. Although also available as a pre-defined physics mode and GUI option, beams and truss structures can also be implemented and accurately simulated with slight extension of the available FEM MATLAB functions …

## 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 …

Stationary heat transfer by conduction and …

## Axisymmetric Modeling Using the Custom Equation Syntax

## Axisymmetric Modeling Using the Custom Equation Syntax

FEATool has been designed to be able to perform MATLAB multiphysics simulations in all spatial dimensions (1D, 2D, and 3D). However, running full 3D simulations often requires a significant amount of computational resources, that is memory and simulation time. It is therefore desirable to find simplifications to reduce …

## Modeling with Custom Equations in the FEATool GUI

## Modeling with Custom Equations in the FEATool GUI

FEATool Multiphysics features an equation parser which allows users to very easily implement and simulate custom systems of equations. The goal as always with FEATool is to make it as easy as possible, the parser can therefore interpret equations written almost as one would on paper. For example a two dimensional …
