Parallel Adaptive FE Methods -- Infrastructure Issues and Solvers
10:00 AM-12:30 PM
Room: Executive Salon 1
The use of solution adaptive methods (mesh refinement and order
enrichment) in conjunction with the fastest parallel computers offers
what is probably the only way to get realistic simulations for most
"Grand Challenge" problems. However, the application of
such adaptive schemes causes special difficulties in terms of data
structures and dynamic memory management issues, mesh partitioning
and dynamic load balancing, and inter-processor communications. etc.
Furthermore, such methods necessitate the development of algorithms
capable of supporting fast and stable solvers for adaptive FE
applications in multiprocessor environments. In this minisymposium,
the speakers will discuss latest developments in these and other
related issues.
