Gmsh is a Windows program known for its powerful 3D finite element mesh generator. Engineers, researchers and students can work on numerical simulation and geometry modeling.
Graphics
The software allows users to define complex geometries with built-in primitives like points, lines, surfaces and volumes. The toolbox also supports importing external CAD models through STEP and IGES formats. It is possible to perform boolean operations, extrusion, rotation and surface recombination to refine shapes.
Moreover, you are able to generate 1D, 2D and 3D meshes using both structured and unstructured techniques. You may define mesh sizes globally or locally for finer control around key features. Algorithms for Delaunay, frontal and transfinite representations ensure high-quality output suitable for accurate simulation results.
Post processing
While primarily a mesh generator, the app also includes robust post-processing tools for viewing simulation results. You can project scalar and vector field visualization as well as animation of time-dependent data. It is possible to load result files and inspect solution behavior within the same interface. Once you finish your work, you are able to export meshes in MSH, STL, VTK and SU2 formats.
Features
- similar to Autodesk Maya, here users have an option to install extensions and plugins;
- suitable for parametric modelling;
- possible to run multiple scripts or mesh jobs with command-line control;
- free to download and use;
- compatible with modern Windows versions.
