geo_domain_indirect(7rheolef) rheolef-6.1 geo_domain_indirect(7rheolef)NAME
geo_domain_indirect_rep - a named part of a finite element mesh
DESCRIPTION
The geo_domain_indirect_rep class defines a container for a part of a finite element mesh. This describes the connectivity of edges or
faces. This class is usefull for boundary condition setting.
IMPLEMENTATION NOTE
The geo_domain_indirect_rep class is splitted into two parts. The first one is the domain_indirect class, that contains the main renumber-
ing features: it acts as an indirection on a geo class(see geo(2)). The second one is the geo class itself, named here the background geo.
Thus, the geo_domain_indirect class develops a complete geo-like interface, via the geo_abstract_rep pure virtual class derivation, and can
be used by the space class (see space(2)).
The split between domain_indirect and geo_domain_indirect is necessary, because the geo class contains a list of domain_indirect. The geo
class cannot contains a list of geo_domain_indirect classes, that refers to the geo class itself: a loop in reference counting leads to a
blocking situation in the automatic deallocation.

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.
