## FEATool Topology Optimization Modeling Example

## FEATool Topology Optimization Modeling Example

This is an advanced model example showing how topology optimization can be implemented and modeled with FEATool. The model has been developed and kindly shared to us by Prof. Shintaro Yamasaki at the Department of Mechanical Engineering of Osaka University [1]. In contrast to standard simulations where the domain and …

## Parametric Structural Mechanics Study with Imported CAD Geometry

## Parametric Structural Mechanics Study with Imported CAD Geometry

This tutorial builds on and continues the previous CAD and Gmsh file import and mesh generation tutorial. A parametric deformation and stress analysis of the imported fixed wrench and spanner CAD model will be performed with a number of different load configuration cases. The following five steps are all that is …

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

## 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 …

## Axisymmetric Stress-Strain Script Modeling

## 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 …

## Parametric Study and Simulation using M-Script Model Files

## Parametric Study and Simulation using M-Script Model Files

Parametric studies can be very useful tools to clearly see how a model or simulation will behave under varying conditions. The following post presents a parametric study of the 3D bracket displacement model introduced previously where both the geometry, in this case plate thickness, and also the applied load force is …
