PROGRAM:
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.
