Parallel adaptive grid refinement on four processors.
The full domain partition facilitates the parallelization of adaptive refinement. Each processor treats its grid exactly like the sequential algorithm, but uses zero as the error estimate in triangles not in its partition. The processors exchange grid information after the refinement is complete to maintain compatibility and degree restrictions across interprocessor boundaries.
