Periodic Boundary Conditions and the Solver Hook Functionality
Periodic Boundary Conditions and the Solver Hook Functionality
This post describes how to implement finite element FEM models with custom periodic boundary conditions in FEATool. A periodic boundary condition can be defined for opposing boundaries so that their values are linked in some defined way. The typical case for two periodic boundaries is to require them to have identical …

Visualization and Postprocessing on Unstructured Grids and Meshes with FEATool Functions
Visualization and Postprocessing on Unstructured Grids and Meshes with FEATool Functions
This post explains how to use MATLAB and the FEATool postprocessing function library to import, plot, and visualize general data on unstructured grids and meshes. Although MATLAB do include visualization functionality for surface and contour plots (with the surf and contour functions), it is currently limited to …
Python Multiphysics Simulations with FEniCS and FEATool
Python Multiphysics Simulations with FEniCS and FEATool
The FEniCS Project is a popular and open-source finite element analysis (FEA) framework for mathematical modeling and physics simulations using the Python programming language. In contrast to specialized solvers (such as OpenFOAM and SU2 for fluid dynamics (CFD), or CalculiX and Code Aster for structural mechanics) …
Running MATLAB FEM and Multiphysics Simulations in Parallel
Running MATLAB FEM and Multiphysics Simulations in Parallel
When given the task to perform many simulations in a larger simulation study or project, such as in optimization studies or parametric studies over several variables as for example described in a parametric simulation script tutorial, one can speed up the overall process significantly by performing the simulations in …
