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.

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).

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 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  specifica-
              tion 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.
