- plot a finite element mesh
geo options mesh[.geo[.gz]]
Plot or upgrade a finite element mesh.
Plot a mesh:
geo box.geo -full
Plot a mesh into a file:
geo square.geo -image-format png
Convert from a old geo file format to the new one:
geo -upgrade - < square-old.geo > square.geo
See below for the geo file format scpecification. The old file format does not
contains edges and faces connectivity in 3d geometries, or edges connectivity
in 2d geometries. The converter add it automatically into the upgraded file
format. Conversely, the old file format is usefull when combined with a
translator from another file format that do not provides edges and faces
- specifies the name of the file containing the input mesh.
The ".geo" suffix extension is assumed.
- read mesh on standard input instead on a file.
- when mesh comes from standard input, the mesh name is not
known and is set to "output" by default. This option allows to
change this default. Useful when dealing with output formats (graphic,
format conversion) that creates auxilliary files, based on this name.
- -I dir
- Add dir to the rheolef file search path. This
mechanism initializes a search path given by the environment variable `
RHEOPATH'. If the environment variable ` RHEOPATH' is not
set, the default value is the current directory.
- Check that element orientation is positive.
- -if format
- -input-format format
- load mesh in format file format, instead of plotting
it. Supported output formats are: geo, bamg, vtk.
When loading from a file, the corresponding suffix extension is
- use gnuplot tool. This is the default.
- use mayavi tool.
- use paraview tool.
- When using a high order geometry, the lattice inside any
element appears. Default is on;
- All internal edges appears, for 3d meshes. Default is
- Fill mesh faces using light effects, when available.
- Rendering mode suitable for red-blue anaglyph 3D
stereoscopic glasses. Option only available with mayavi or
- shrink elements (with paraview only).
- cut by plane and clip (with mayavi or
- Show or hide labels, boundary domains and various
annotations. By default, domains are showed with a specific color.
- output mesh on standard output stream in geo text file
format, instead of plotting it.
- Convert from a old geo file format to the new one.
- output mesh on standard output stream in gmsh text file
format, instead of plotting it.
- -image-format string
- The argument is any valid image format, such as bitmap
png, jpg, gif, tif, ppm, bmp or
vectorial pdf, eps, ps, svg image file
formats. this option can be used with the paraview and the
gnuplot renders. The output file is e.g. basename.png
when basename is the name of the mesh, or can be set with the
- -resolution int int
- The argument is a couple of sizes, for the image
resolution. This option can be used together with the -image-format
for any of the bitmap image formats. This option requires the
- -subdivide int
- Subdivide each edge in k parts, where k is
the prescribed argument. The new vertices are numbered so that they
coincide with the P k Lagrange nodes. It can be combined with the
-geo option to get the subdivided mesh. In that case, default value
is 1, i.e. no subdividing. It can also be combined with a graphic option,
such that -gnuplot or paraview: When dealing with a curved
high order geometry, k corresponds to the number of points per edge
used to draw a curved element. In that case, this option is activated by
default and value is the curved mesh order.
- check for a domain named "boundary"; If this
domain does not exists, extract the boundary of the geometry and append it
to the domain list. This command is usefull for mesh converted from
generators, as bamg, that cannot have more than one domain
specification per boundary edge.
- Specifies the coordinate system. Usefull when converting
from bamg or gmsh format,.
- print messages related to graphic files created and command
system calls (this is the default).
- does not print previous messages.
- clear temporary graphic files (this is the default).
- does not clear temporary graphic files.
- execute graphic command (this is the default).
- does not execute graphic command. Generates only graphic
files. This is usefull in conjuction with the "-noclean"
- used for debug purpose.
- print the mesh size, i.e. the number of elements (resp. of
vertices) and then exit.
- print the smallest (resp. largest) edge length and then
- print the smallest (resp. largest) element measure and then
