Inverse Modeling and Parameter Search Using the fzero MATLAB function
Inverse Modeling and Parameter Search Using the fzero MATLAB function
FEATool Multiphysics not only features an easy to use graphical user interface (GUI), but is also fully compatible with the MATLAB scripting language. Models can both be saved in binary format and MATLAB m-script files (every action in the GUI is recorded and has a one to one corresponding FEATool MATLAB function …
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 deflection model introduced previously where both the geometry, in this case plate thickness, and also the applied load force is …
