3D finite element mesh generator with built-in CAD engine and post-processor
Synopsis
gmsh [file(s)] [option(s)]
Description
Gmsh is a 3D finite element mesh generator with a build-in CAD engine and post-processor. Its design goal is to provide a fast, light and user-friendly meshing tool with parametric input and flexible visualization capabilities.
Gmsh is built around four modules (geometry, mesh, solver and post-processing), which can be controlled with the graphical user interface, from the command line, using text files written in Gmsh's own scripting language (.geo files), or through the C++, C, Python, Julia and Fortran application programming interface.
Geometry Options
- -0
Output model, then exit.
- -tol float
set geometrical tolerance.
Mesh Options
- -1, -2, -3
perform 1D, 2D or 3D mesh generation, then exit.
- -o file
specify output file name.
- -format string
