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 …
Automatic Unstructured Quadrilateral Grid Generation
Automatic Unstructured Quadrilateral Grid Generation
QuadMesh is a MATLAB cross compatible automatic and unstructured quadrilateral grid generation code, developed to be used with the FEATool Multiphysics MATLAB Finite Element simulation toolbox. Using quadrilateral grid cells are often advantageous to simplex or triangular cells in that they can provide somewhat more …
Calling the External Grid Generator Triangle from FEATool
Calling the External Grid Generator Triangle from FEATool
Please Note that the gridgen_triangle function has been fully integrated with the both the FEATool GUI and CLI, and embedded in the gridgen function. See the FEATool-Triangle Mesh Generator Integration post for more details. FEATool Multiphysics supports calling external programs for grid generation, solvers, and …
Creating Structured Grids Using FEATool MATLAB Functions
Creating Structured Grids Using FEATool MATLAB Functions
FEATool includes and per default uses the distmesh grid generation routines to automatically generate simplical triangular or tetrahedral grids for implicit geometries. However, the computational finite element library in FEATool also supports FEM shape functions for structured grids (quadrilaterals in 2D and hexahedra …
