# cs\_solver(1)

Main program of Code\_Saturne.

## NAME

cs\_solver - Main program of Code\_Saturne.

## SYNOPSIS

**cs\_solver**\

## DESCRIPTION

The **cs\_solver** program is the main part of Code\_Saturne. It solves the Navier-Stokes equations, on a mesh given by the **preprocessor\_output** created by the Code\_Saturne preprocessor.

## OPTIONS

- \--solcom

  **Stand-alone kernel with "geomet" mesh in SolCom format (obsolete).**

- \--mpi \[appnum\]

  **Use MPI for parallelism or coupling. In case of code coupling,** **appnum** gives the number of this application (default: 0).

- \-q, --quality

  **Mesh quality verification mode.**

- \--cwf \<criterion\> \[--post\]

  **Cut warped faces. Set the** **post** option to activate the post-processing related to the cutting of warped faces.

- \--benchmark \[--mpitrace\]

  **Elementary operations performance. If the** **mpitrace** option is set, operations are done only once for light MPI traces.

- \--log

  **Output redirection for rank -1 or 0. Differents possibilities are: 0** for standard output and 1 for output in **listing** (default)

- \--logp

  **Output redirection for rank \> 0. Differents possibilities are: -1 to** remove output (default), 0 for no redirection (if independant terminal, debugger type) and 1 for output in **listing\_n\<rank\>**

- \-p, --param \<file\_name\>

  **Parameter file.**

- \--version

  **Print version number.**

- \-h, --help

  **Print a usage message and exit.**

## ENVIRONMENT

- CS\_FIC\_MEM

  Name of memory operations trace file.
