Comparison of the DistMesh, Gmsh, and Triangle Mesh Generators
Comparison of the DistMesh, Gmsh, and Triangle Mesh Generators
Having implemented and fully integrated a uniform MATLAB mesh generation framework with FEATool Multiphysics, it is now both very easy and convenient to directly compare mesh generation codes and algorithms with each other. In the following post the DistMesh, Gmsh, and Triangle open source mesh generators are compared …
Using Mixed Robin Boundary Conditions in FEATool
Using Mixed Robin Boundary Conditions in FEATool
Robin boundary conditions or mixed Dirichlet (prescribed value) and Neumann (flux) conditions are a third type of boundary condition that for example can be used to implement convective heat transfer and electromagnetic impedance boundary conditions. In the following it will be discussed how mixed Robin conditions are …

FEATool Multiphysics 1.7.1 Toolbox Update with Gmsh and Triangle GUI Integration
FEATool 1.7.1 Update An update to FEATool Multiphysics (v1.7.1) is now available featuring many stability, GUI, and performance improvements. Moreover, a redesigned and simplified mesh and grid generation toolbar has been introduced, including built-in support for the external Gmsh and Triangle mesh generators. New …
MATLAB GUI and CLI Gmsh Mesh Generator Integration with FEATool
MATLAB GUI and CLI Gmsh Mesh Generator Integration with FEATool
Gmsh Mesh Generator Integration FEATool Multiphysics features full integration with the Gmsh grid and mesh generation software [1][2]. Both 2D and 3D GUI, and also MATLAB command line interface (CLI) use and MATLAB scripts are supported (with the gridgen and impexp_gmsh functions). Advantages of using Gmsh compared to …
Creating 3D Semi-Structured Grids Using Extrusion
Creating 3D Semi-Structured Grids Using Extrusion
When generating grids and meshes for fully three-dimensional structures with constant cross section in one or more directions, it is often advantageous to first create a two dimensional grid and extrude it to 3D, rather than generate a full 3D grid directly. By using the extrusion technique more control over the grid …
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 …
CAD File Import, Mesh, and Grid Generation with Gmsh
CAD File Import, Mesh, and Grid Generation with Gmsh
Gmsh is a popular cross platform and open source mesh generation software. Gmsh supports many CAD file formats such as STEP, IGES, and STL, as well as also includes a variety of integrated mesh generation algorithms, such as from Triangle, Tetgen, and Netgen, Gmsh can be used together with FEATool to allow for more …
