# mtst(1)

test the consistency of source meshes

## NAME

**mtst** - test the consistency of source meshes

## SYNOPSIS

```
mtst [options] [mfile] [lfile]
```

## DESCRIPTION

**The mtst program checks, in a sequential way, the consistency of a** **Scotch source mesh and, in case of success, outputs some statistics** **regarding edge weights, node and element vertex weights, and node** **and element vertex degrees.**

**Source mesh file** *mfile* **can only be a centralized mesh file. The** **resulting statistics are stored in file** *lfile***. When file names are** **not specified, data is read from standard input and written to** **standard output. Standard streams can also be explicitly** **represented by a dash '-'.**

**When the proper libraries have been included at compile time, mtst** **can directly handle compressed meshes, both as input and output. A** **stream is treated as compressed whenever its name is postfixed with** **a compressed file extension, such as in 'brol.msh.bz2' or '-.gz'. The** **compression formats which can be supported are the bzip2 format** **('.bz2'), the gzip format ('.gz'), and the lzma format ('.lzma').**

## OPTIONS

- **-h**

  **Display some help.**

- **-V**

  **Display program version and copyright.**

## EXAMPLE

**Test the consistency of mesh brol.msh:**

```
    $ mtst brol.msh
```
