1) Adapt the intial mesh until a quality metric, e,g, a priori error bound, is satisfied

2) Solve the problem on a series of adapted meshes until a quality metric, e.g. a posteriori error bound, is satisfied

3) Solve the problem on a hierarchy of adapted meshes generated to satisfy a quality metric using multigrid
