NAME¶
geo - plot a finite element mesh
SYNOPSIS¶
geo options mesh[.geo[.gz]]
DESCRIPTION¶
Plot or upgrade a finite element mesh.
EXAMPLES¶
Plot a mesh:
geo square.geo
geo box.geo
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
connectivity.
- filename
- 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.
- -name
- 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.
- -Idir
- -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
- 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
assumed.
RENDER SPECIFICATION¶
- -gnuplot
- use gnuplot tool. This is the default.
- -mayavi
- use mayavi tool.
RENDER OPTIONS¶
- -lattice
- -nolattice
- When using a high order geometry, the lattice inside any
element appears. Default is on;
- -subdivide int
- When using a high order geometry, the number of points per
edge used to draw a curved element. Default value is the mesh order.
- -full
- -nofull
- All internal edges appears, for 3d meshes. Default is
off;
- -fill
- -nofill
- Fill mesh faces using light effects, when available.
- -stereo
- -[no]stereo
- Rendering mode suitable for red-blue anaglyph 3D
stereoscopic glasses. Option only available with mayavi.
- -cut
- -nocut
- cut by plane and clip (with mayavi only).
- -geo
- output mesh on standard output stream in geo text file
format, instead of plotting it.
- -upgrade
- Convert from a old geo file format to the new one.
- -gmsh
- 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 or vectorial ps or pdf
image file formats, and that could be handled by the corresponding render.
The output file is e.g. ` @emph{basename'.png} when @emph{basename}
is the name of the mesh, or can be set with the -name option.
OTHERS OPTIONS¶
- -add-boundary
- 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.
- -verbose
- print messages related to graphic files created and command
system calls (this is the default).
- -noverbose
- does not print previous messages.
- -clean
- clear temporary graphic files (this is the default).
- -noclean
- does not clear temporary graphic files.
- -execute
- execute graphic command (this is the default).
- -noexecute
- does not execute graphic command. Generates only graphic
files. This is usefull in conjuction with the "-noclean"
command.
- -check
- -dump
- used for debug purpose.
INQUIRE OPTIONS¶
- -min-element-measure
- -max-element-measure
- print the smallest (resp. largest) element measure and then
exit.
