Hello, I was once told by a colleague before running an optimisation with optistruct to use the control parameters '-ncpu 8 -core IN'. This was to make the simulation run faster. To my understanding '-ncpu 8' ensures the simulation utilises the computers 8 cores. However, I do not know what the '-core IN' does. Can anyone offer any insight into the meaning behind this and if it actually helps with the simulation speed. Additionally, if there are any other optistruct option inputs that could be used to speed up the simulation then please let me know what they are. Thank you in advance.
hallo everybody, I'm using HW 12 and have already run some analysis (mostly static analysis). I use a Intel i7 3770k cpu with 4 cores and hyperthreading. I use the "-ncpu 8" option when running radioss, to minimize running time. But windows still shows only 50% cpu usage in the task manager. I also tried to use the "-nt 8" option, but it didn't make any difference. My professor in university told me these run options, but doesn't know himself, why the cpu ist only at 50%. Does anybody know, how to get 100% cpu usage when running Radioss 12? Is there some kind of parameter in the control cards maybe? Thanks in advance for some help!
