Andre Cote writes:
Depending on the type of problems we solve ( structure only, fluid only,
fluid-structure, etc.), and the type of solutions we are interested in
(eigenvalue or forced problems), we use different calculations schemes.
But, basically, the main bottleneck for every path comes down to two
situations:
1. Solving Ax = b for A symmetric and real (double precision)
file name: vibrobox.rsa
How large ? 12328 DOFS
What is the structure like ? symmetric with large bandwidth
What structural problem ? flexible box (structure only)
2. Solving Ax = b for A symmetric and complex (double precision)
file name: mplate.csa
How large ? 5962 DOFS
What is the structure like ? symmetric
What structural problem ? multi-layer plate (that is
a plate-air-poroelastic-air-plate system)
Many solves are required (a few to 5000).
