Dear Sirs,
I'd like to ask You a new question on this topic which arises from the insight of given aswers.
I guess that my opinion about solver speed issue was not far from true: on today computer near all static/modal problems cam be solved quite easly in a proportional to precision ammount...
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...
Now that is quite a long time I'm using FEM code, but there is still an opened question.
In a fem job the a big amount of time seems to be used for linear system solution (from 70% to 90% in bigger problems).
Now I know that MSC Nastran can solve both directly and iteratevly those linear...
