We are developing a framework for adaptive and parallel computation
that is capable of (i) generating three-dimensional unstructured
meshes of tetrahedral elements, (ii) automatically refining
and coarsening these meshes, (iii) partitioning the computation
into subdomains that may be processed in parallel, and (iv)
maintaining a balanced parallel computation through element
migration. Mesh generation is supported by a hierarchical database
which suuports both h- and p-refinement. The database
is connected to geometrical modeling procedures and to a parallel
library having capabilities for processor scheduling and reassignment.
Special dynamic load-balancing strategies appropriate to this
enviroment are described. Applications of the parallel adaptive
finite element procedures to flow problems are described.
