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.
