    Command:

    geo

    
    
    

    SYNOPSIS

                   geo options mesh[.geo]
    
    
    

    DESCRIPTION

           Plot a 2d or 3d finite element mesh.
    
           The  input  file  format  is  described  with the geo class manual (see
           geo(3)).
    
    
    

    EXAMPLE

           Enter commands as:
    
                   geo -vtk bielle.geo
                   geo -vtk -fill bielle.geo
    
           or, for 2D meshes:
    
                   geo -plotmtv square.geo
    
    
    

    INPUT FILE SPECIFICATION

           filename
                  specifies the name of the file containing the  input  mesh.  The
                  ".geo" extension is assumed.
    
           -Igeodir
                  add  geodir to the mesh 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 (see geo(3)).
    
           -      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.
    
    
    

    INQUIRE OPTIONS

           -size  print the number of elements in the mesh and exit.
    
           -n-node
                  print the number of nodes in the mesh and exit.
    
                  use Mayavi.  This is the default.
    
           -plotmtv
                  use plotmtv tool.

           -stereo
                  Rendering  mode  suitable  for red-blue anaglyph 3D stereoscopic
                  glasses.  Option only available with mayavi.
    
           -grid  rendering mode. This is the default.
    
           -fill  rendering mode. Fill mesh faces using light effects when  avail-
                  able.
    
           -shrink
                  rendering mode. Shrink 3d elements (with vtk only).
    
           -tube  rendering mode. All edges appears as tubes (with vtk only).
    
           -ball  rendering mode. Vertices appears as balls (with vtk only).
    
           -full  rendering mode. All edges appears (with vtk only).
    
           -cut   rendering  mode.  cut  by plane and clip (with vtk only).  Works
                  with '-full', '-tube' or '-ball' modes.  Does not clip mesh with
                  '-fill'  and  '-grid'  modes.   Does not work yet with '-shrink'
                  mode.  This option is still in development.
    
           -origin x [y [z]]
                  set the origin point of the cutting plane when  using  with  the
                  '-cut' option.  Default is (0.5,0.5,0.5).
    
           -normal nx [ny [nz]]
                  set the normal vector of the cutting plane.  when using with the
                  '-cut' option.  Default is (1,0,0).
                  instead of plotting it.
    
           -tegen output mesh on stream in tegen  text  file  format,  instead  of
                  plotting it (TODO).
    
           -mmg3d output mesh on standard output stream in mmg3d text file format,
                  instead of plotting it.
    
           -cemagref
                  output mesh on standard output stream in cemagref text file for-
                  mat, instead of plotting it. Notices that the mesh does not con-
                  tains the topographic elevation. If you want to include the ele-
                  vation,  in the output, use the field command with the -cemagref
                  option.
    
           -upgrade
                  edges and faces are numbered. This numbering is required for the
                  quadratic approximation.
    
           -ndigit int
                  number  of digits used to print floating point values when using
                  the '-geo' option.  Default depends upon the  machine  precision
                  of  the  Float type.  @item -output-as-double Avoid variation of
                  output float formats when using high precision  doubledouble  or
                  bigfloat  classes.   This option is used for non-regression test
                  purpose.
    
    
    

    INPUT FORMAT OPTIONS

           -input-geo
                  read the mesh in the '.geo' format.  This is the default.
    
           -input-bamg
                  read the mesh in the '.bamg' format.  Since edges are  not  num-
                  bered  in  '.bamg'  format, this file format is not suitable for
                  using P2 elements.  This format is  supported  only  for  format
                  conversion  purpose.  See -upgrade for edge numbering while con-
                  verting to '.geo'.
    
           -input-gmsh
                  read the mesh in the '.msh' format.  Since edges in 2D and faces
                  in 3D are not numbered in '.msh' format, this file format is not
                  suitable for using P2 elements.  This format is  supported  only
                  for  format conversion purpose.  See -upgrade for edge numbering
                  while converting to '.geo'.
                  able  for  using P2 elements.  This format is supported only for
                  format conversion purpose.   See  -upgrade  for  edge  numbering
                  while converting to '.geo'.
    
           -input-grummp
                  read  the mesh on standard input stream in grummp text file for-
                  mat.  The .g grummp file format is  defined  grummp  '.template'
                  specification file
    
                  newfile g
                  "grummp"
                  "2" nverts ncells nbfaces
                  verts: coords
                  cells: verts region
                  bdryfaces: verts bc
    
                  Conversely,  for  tridimensionnal meshes, the grummp '.template'
                  specification file is:
    
                  newfile g
                  "grummp"
                  "3" nverts ncells nbfaces
                  verts: coords
                  cells: verts region
                  bdryfaces: verts bc
    
                  Such files can be generated with the tri and tetra  grummp  mesh
                  file generators. The grummp mesh generators suport multi-regions
                  geometries. These regions are translated to  bi-  or  tri-dimen-
                  sional  domains,  that  are  no boundary domains.  A file format
                  conversion writes:
    
                  geo -input-grummp -geo -upgrade -noverbose - < hex-multi.g > hex-multi.geo
    
           -input-qmg
                  output mesh on standard output stream in qmg text  file  format.
                  instead  of plotting it.  Since edges are not numbered in '.qmg'
                  format, this file format is not suitable for using P2  elements.
                  This  format  is  supported  only for format conversion purpose.
                  See -upgrade for edge numbering while converting to '.geo'.
    
           -dmn domain-names-file
                  An auxilliary '.dmn' file defining the boundary domain names  as
                  used  by  rheolef  could  be used, since bamg, mmg3d, tetgen and
                  grummp use numeric labels for  domains.  Example  of  a  'multi-
                  domain.dmn' with two regions and four boundary domains file:
    
                  EdgeDomainNames
                  cat multi-domain.g multi-domain.dmn | \
                  geo -input-grummp -upgrade -geo -  > multi-domain.geo
    
                  If  this file is not provided, boundary domains are named bound-
                  ary1, boundary2, ...   and  region  domain  are  named  region1,
                  region2,  ...  The tridimensionnal domain name file contains the
                  FaceDomainNames and VolumeDomainNames keywords, for boundary and
                  region domains, respectively.
    
           -input-cemagref
                  read  the  mesh  in  the  '.cemagref'  format.  Notices that the
                  reader skip the topographic elevation informations.  If you want
                  to  load  the  elevation, use the field command with the -input-
                  cemagref option.
    
    
    

    OTHERS OPTIONS

           -verbose
                  print messages related to graphic files created and command sys-
                  tem 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.
    
    
    

    GRAPHIC OUTPUT FILE

           You can generate a postscript, latex or Fig output of your mesh,  using
    
           p      point
    
           e      edge
    
           t      triangle
    
           q      quadrangle
    
           T      tetrahedron
    
           P      prism
    
           H      hexaedron Then, we have the vertex indexes.  A vertex  index  is
                  numbered in the C-style, i.e. the first index is numbered 0.  An
                  edge is a couple of index.
    
           Geo version 1 file format (obsolete) does neither give any  information
           about  edges  for  2d  meshes  nor for faces in 3d. This information is
           requiered for maintaining P2 approximation file in  a  consistent  way,
           since edge and face numbering algorithm should vary from one version to
           another, and thus may be stored on file.
    
           Nevertheless, geo version 1 file format is still supported, since it is
           a convenient way to build and import meshes (see geo(1)).
    
           A sample mesh is in version 1 writes
    
                   mesh
                   1 2 4 2
                   0 0

                   0 1
                   t   0 1 3
                   t   1 2 3
    
           the same in version 2
