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 of time.
Only really tough problems (more expensive) like those due to non-linearity, speed time response (crash like) or CFD (high reynolds, transport phenomena, combustion ....) really need computing perormances.
I know that several commercial code offer several solution methods (explicit/implicit, direct/iterative), or even Multigrid/AMG methods.
Now here comes my question and iterest:
is there a Return On Investement of those codes one can be reasonably confident to achive?
I long for your prompt reply!
With best regards,
mastro
