NAME¶
Gmsh - 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
- set output mesh format (auto, msh, msh1, msh2, msh4, unv, vrml, stl, mesh, bdf, med, ...).
- -bin
- use binary format when available.
- -saveall
- save all elements (discard physical group definitions)
- -algo string
- select mesh algorithm (meshadapt, del2d, front2d, del3d, front3d, hxt, ...).
- -parametric
- save nodes with their parametric coordinates.
- -part int

- -clscale float
- set global mesh element size scaling factor.
- -clmin float
- set minimum mesh element size.
- -clmax float
- set maximum mesh element size.
- -rand float
- set random perturbation factor.
- -bgm file
- load the post-processing view in file as the current background mesh.
- -check
- perform various consistency checks on mesh.
POST-PROCESSING OPTIONS¶
- -combine
- combine input views into multi-time-step ones.
DISPLAY OPTIONS¶
