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 grid 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 advanced visualization capabilities.

Gmsh is built around four modules: geometry, mesh, solver and post-processing. The specification of any input to these modules is done either interactively using the graphical user interface or in ASCII text files using Gmsh's own scripting language.

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

partition the mesh after batch mesh generation.

-smooth int

set number of mesh smoothing steps.

-order int

set mesh order.

-clscale float

set global scaling factor to the mesh characteristic lengths in the model.

-clmin float

Set minimum characteristic length.

-clmax float

Set maximum characteristic length.

-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
