I've not really used the screen command, but having taken a quick look at it, I think you'll need to describe more about the specifics of what you're doing so that there's a chance somebody might be able to comprehend and answer your question.
Did you try first with nohup ?
Also a warning, I suppose you run ocean for different Hierarchy. Indeed, if you run spectre for a same design, it will overwrite the result directory (psf) so you will get only the last simulation.
NB : if you want a clearer answer, ask a clear/detailed question.
ocean page 33
For example, while using OCEAN with the -nograph option, your
oceanScript.ocn file must have an exit() statement at the end. Otherwise, OCEAN
hangs. The reason for this is that when the workbench is started in the non-graphical mode,
it does not redirect standard I/O as it normally does; instead, it lets the SKILL human interface
(HI) handle the standard I/O. HI expects an explicit exit() statement at the end of the
OCEAN script and OCEAN exits only when it detects an exit() at EOF.
In reply to ebecheto:
for clarification that was the context of the question
foreach myvariable ("case1" "case2" "case3")
ocean -nograph < oeanScript.ocn
the problem was that the the ocean script was invoked only for case1, and the cause was that ocean hanged since there was no exit() statement at the end of the oceanScript.ocn file
