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.
INPUT FILE SPECIFICATION
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.
INPUT FORMAT OPTIONS
-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.
-paraview
use paraview tool.
RENDER OPTIONS
-[no]lattice
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.
-[no]full
All internal edges appears, for 3d meshes. Default is off;
-[no]fill
Fill mesh faces using light effects, when available.
-[no]stereo
Rendering mode suitable for red-blue anaglyph 3D stereoscopic glasses. Option only available with
mayavi or paraview.
-[no]shrink
shrink elements (with paraview only).
-[no]cut
cut by plane and clip (with mayavi or paraview only).
-[no]label
Show or hide labels, boundary domains and various annotations. By default, domains are showed
with a specific color.
OUTPUT FILE FORMAT OPTIONS
-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, 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 -name option.
-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 paraview
render.
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.
-rz
-zr Specifies the coordinate system. Usefull when converting from bamg or gmsh format,.
-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
-size
-n-vertex
print the mesh size, i.e. the number of elements (resp. of vertices) and then exit.
-hmin
-hmax print the smallest (resp. largest) edge length and then exit.
-min-element-measure
-max-element-measure
print the smallest (resp. largest) element measure and then exit.
