	def write_background_mesh(background_mesh, out_stem):
	"""Write a background mesh to a file.
	This writes the mesh in tetgen format (X.b.node, X.b.ele) and a X.b.mtr file
	containing the target size for each node in the background mesh.
	"""
	mtr_content = [f"{background_mesh.n_points} 1"]
	target_size = background_mesh.point_data["target_size"]
	for i in range(background_mesh.n_points):
	mtr_content.append(f"{target_size[i]:.8f}")
	write_background_mesh(bg_mesh, 'bgmesh.b')
