NAME
ecs - Code_Saturne preprocessor
SYNOPSIS
ecs -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)
- -echo-comm [n]
- Print headers of sent messages (and n first/last elements if n is given)
- -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
- -o, -out [<file>]
- Redirect terminal output to a file (default file: output.ecs)
- -perio, -periodic <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
- -ens, -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)
