NAME
cs_preprocess - Code_Saturne preprocessorSYNOPSIS
cs_preprocess -m <file> [-sc] [options]DESCRIPTION
Code_Saturne preprocessor reads meshes from several formats. It enables non-conforming joining and periodicity handling, as well as some postprocessing for mesh checking.OPTIONS
- -m, --mesh <file>
- Preprocessor input mesh file (mesh file format determined automatically by filename extension or forced by -format sub-option)
- -sc, --sim-comm
- simulate messages without file output
General options
- --cwd <directory>
- working directory (if different from current directory)
- -h, --help
- Print a usage message and exit.
- -i, --in [<file>]
- Command line completed by a file (default file: standard input)
- --int-face [<sub-options>]
- Count and display interior faces these faces may be selected with face-selection sub-options
- -j, --join [<sub-options>]
- Join non-conforming faces; select faces to join with face-selection sub-options
- --log [<file>]
- Redirect terminal output to a file (default file: preprocessor.log)
- -p, --perio <sub-options>
- Mesh periodicity defined by argument; joining sub-options for tolerances and selection of periodic faces with face-selection sub-options
- --reorient
- If necessary, correct orientation of cells and faces
- --version
- Print version number
Postprocessing options
- --case <name>
- Case name (without this option, the default name is: preprocess)
- --cgns [<sub-options>]
- CGNS geometry output
- --ensight [<sub-options>]
- EnSight Gold geometry output
- --med [<sub-options>]
- MED 2.3 geometry output
Mesh selection sub-options (-m, --mesh)
- --format <keyword>
- Selection of mesh file format
- --num <n>
- Selection of mesh number in file (if the format allows it)
- --grp-cel <keyword>
- Add groups of cells (based on format features/conventions)
* based on sections: keyword "section"
* based on zones: keyword "zone" - --grp-fac <keyword>
- Add groups of faces (based on format features/conventions)
* based on sections: keyword "section"
* based on zones: keyword "zone"
Available mesh formats (-m, --mesh; --format)

Postprocessing selection sub-options (--cgns, --ensight, --med)
- --discard-poly
- discard polygonal faces (wth more than 4 edges) or polyhedra
- --simple
- force mesh output on a single part (EnSight) or section (CGNS)
- --text
- force text output (EnSight)
- --big-endian
- force binary output to big-endian (EnSight)
- --color-to-group
- transform colors to groups (MED)
- --volume
- activate output of volume mesh (by default if -boundary or -info not given)
- --boundary
- activate output of boundary mesh (by default if -volume or -info not given)
- --info
- activate output of information meshes (by default if -volume or -boundary not given)
Periodicity sub-options (-perio, -periodic)
- --trans <tx ty tz>
- translation vector
- --rota --angle <alpha> --dir <dx dy dz> [--invpt <px py pz>]
- rotation defined by an angle (in degrees) and a direction vector, and eventually by an invariant point (origin by default)
- --rota --matrix <mij> [--invpt <px py pz>]
- rotation defined by the rotation matrix (given line by line), and eventually by an invariant point (origin by default)
Non-conformal face joining sub-options (-j, --join, -p, --perio)
- --fraction <real number>
- fraction of the length of the smallest edge under which we consider that vertices may be fused (default value: 0.1)
- --plane <real number>
- minimal cosine of the normals of 2 coplanar faces (default value: 0.8)
- --semi-conf
- fast joining algorithm (allowed if faces already share vertices)
Face selection sub-options (for joining, selection, and periodicity)
- --color <number(s)>
- color numbers of faces to select
- --group <name(s)>
- group names of faces to select
- --invsel
- invert selection
ENVIRONMENT
- CS_PREPROCESS_MIN_EDGE_LEN
- Length under which an edge is considered degenerate (default: 1.e-15).
- CS_PREPROCESS_MEM_LOG
- Name of memory operations trace file.
- CS_PREPROCESS_IGNORE_IDEAS_COO_SYS
- Ignore I-deas coordinate systems.
- CS_PREPROCESS_JOIN_MAX_SUB_FACES
- Number of new faces of an initial face above which we consider that conformal joining face reconstruction has gone into an infinite loop (default: 100)
