# mkgeo\_couette(1rheolef)

mesh of the Couette geometry (rheolef-7.2)

## NAME

mkgeo\_couette - mesh of the Couette geometry (rheolef-7.2)

## SYNOPSIS

```
mkgeo_couette n
```

## EXAMPLE

The following command build a triangle based 2d unstructured mesh of the Couette geometry

```
    mkgeo_couette 10
    geo couette-10.geo
```

## DESCRIPTION

This command is useful when testing fluid mechanics programs on simple geometries. It calls the `bamg` as unstructured mesh generator.

## THE GEOMETRY

The geometry is a unit disk with a circular hole with diameter 1/2.

## BOUNDARY DOMAINS

The boundary domains are `interior` and `exterior`.

## IMPLEMENTATION
