More on solver speed: case study
(OP)
Dear Sirs,
I'm looking for an advice: is there a list of structural linear case study usable to test commercial FEM packages, like "driven cavity" or "facing step" for CFD codes.
Another question: is solver speed cost effective in Your own activity?
Is there anyone using a dedicated cluster for nonlinear structural dynamics?
Regards,
Mastro

in my company instead solver speed is not of primary importance, because we have lots of automated routines which allow batch processing overnight. There is one exception, though: the CFD department runs on a dedicated cluster.
It's more a question of memory: with 1 GB, I am limited in the size of the problem I can handle: it's a "pass-through" criterion: if the solver CAN start, no matter (well, approximatively of course...) how much time it will take it will be much faster than testing a prototype and much cheaper than to afford the risk of a failure... But if it CAN'T, then I may have the fastest processor in the world but it will serve to nothing at all...

The CFD guys run multithreaded jobs locally, I don't know any details.
Solve time is a big issue - if my models would run in 10 seconds instead of half an hour then I'd be far more productive, as I wouldn't be reading eng-tips, or get otherwise distracted!, between runs.
Cheers
