Grid Generation with Scaling
Grid Generation with Scaling
For models and geometries where either one axis direction dominates, such as for long or tall geometry objects, or simulations where the solution is expected to not to vary in certain directions, such as some flow situations, it can be very beneficial to use anisotropic grids. By using elongated mesh elements the total …
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 …
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 …
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 …
Triangle Mesh Generator GUI and CLI Integration with FEATool
Triangle Mesh Generator GUI and CLI Integration with FEATool
FEATool-Triangle Mesh Generator Integration The fast and efficient 2D mesh and grid generator, Triangle, by J.R. Shewchuk’s is fully integrated with FEATool Multiphysics [1][2][3]. Both MATLAB command line interface (CLI) usage is supported with the gridgen function, as well as FEATool GUI usage by selecting the …
Interactive 3D Data and Simulation Visualizations with Plotly and MATLAB
Interactive 3D Data and Simulation Visualizations with Plotly and MATLAB
FEATool can be used to easily generate interactive surface, contour, arrow, and other visualizations of unstructured mesh and simulation data in 1D, 2D, and 3D. As FEATool also supports Plotly as rendering and visualization engine it is possible to create, interactively explore, and share simulation and unstructured …
