Different Ways of Working with FEATool and FEM Simulations
FEATool Multiphysics is unique in that it allows several different ways for users to work with FEM modeling and simulation. The whole spectrum from using the high-level graphical user interface down to low-level access of the fundamental matrices of the underlying finite element FEM discretization is possible. On top …
Implementing Custom and User Defined Finite Element Shape and Basis Functions
FEATool has been designed with flexibility and user customization in mind allowing for solving custom equations, calling external solvers, grid generators, and post processing tools, and allowing for both MATLAB m-script as well as GUI based modeling. This post shows how to easily define custom finite element shape …
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 …
