We describe and test an adaptive algorithm for evolution problems that employs a sequence of “blocks” consisting of fixed, though non-uniform, space meshes. This approach offers the advantages of adaptive mesh refinement but with reduced overhead costs associated with load balancing, re-meshing, matrix reassembly, and the solution of adjoint problems used to estimate discretization error and the effects of mesh changes. A major issue with a block-adaptive approach is determining block… CONTINUE READING
