create source meshes

## Synopsis

mmk_m2[options] [-gcfile]dimX dimY[ofile]mmk_m3[options] [-gcfile]dimX dimY dimZ[ofile]

## Description

The **mmk_*** programs create source mesh files for some common, regular topologies.

**mmk_m2** creates a 2D regular mesh of *dimX* times *dimY* elements and (*dimX*+1) times (*dimY*+1) nodes, such that element (i,j) is connected to nodes (i,j), (i,j+1), (i+1,j) and (i+1,j+1).

**mmk_m3** creates a 3D regular mesh of *dimX* times *dimY* times *dimZ* elements and (*dimX*+1) times (*dimY*+1) times (*dimZ*+1) nodes, such that element (i,j,k) is connected to nodes (i,j,k), (i,j,k+1), (i,j+1,k), (i,j+1,k+1), (i+1,j,k), (i+1,j,k+1), (i+1,j+1,k) and (i+1,j+1,k+1).

## Options

- -g
*cfile* Output graph vertex coordinates (that is, geometry data to be used by

**gout**(1)) in file*cfile*.- -h
Display some help.

- -V
Display program version and copyright.

## Example

Create a mesh of 5x7 elements, along with its geometry:

$ mmk_m2 5 7 -g/tmp/m5x7.xyz /tmp/m5x7.msh
