# mmk\_m3-int64(1)

create source meshes

Part of [mmk\_m2(1)](/mmk_m2/1.md).

## NAME

**mmk\_m2, mmk\_m3** - 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 grid 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 grid 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)](/gout/1.md)) 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
```
