Meshes

This repository contains Python/Gmsh code to create boundary meshes for use with Bempp.

These meshes can be made using the following Python code.

import meshes
cake = meshes.Cake(h=0.1)

The parameter h sets the mesh size.

The Gmsh geo string for this mesh can be generated by calling:

cake.to_geo_string()

A Bempp grid can be generated by calling:

cake.to_bempp_grid()

This will raise an ImportError if Bempp is not installed.
