Hi,
I'm trying to solve a big modell with a 64bit windows laptop, 2* i7 cpu and 8gb ram in radioss bulkdata. I have 20 loadcases but 10 of them are buckling analysis and therefore the calculation is running for approx. 4 days now. In the task manager, I've seen that ony 2% of the cpu is in use but 5GB of RAM because before starting the calculation, I've entered 5000 for the memory options-upper limit.
My question is know, if it is possible to accelerate the calculation by using more cpu or ram or both?
Btw. sind a few days, always the same .rs~ files are created and delated (something_s53.rs~ and something_s57.rs~ )
Hi Musti
run option for CPUs is -ncpu
run option for RAM is -len (MB)
Just looking for in OptiStruct Help

oh tnx, just found it /emoticons/default_smile.png' alt=':)' srcset='/emoticons/smile@2x.png 2x' width='20' height='20'>
You should learn a bit about solution logic of the model. There are 3 options:
1. Incore Processing
2. Outcore Processing
3. Mincore Processing
If your ram level is enough, incore is the best, no extra swap space usage. Outcore uses both ram and swap space in a balanced way. Mincore uses mostly the swap space and leastly the ram.
hi,
I am not able to find the len (MB) option. Is it in radioss solvere run manager or has to be set in the hyperworks interface before starting the simulation?
8G ram is just for .... playstation! Don't expect something serious with this hardware /emoticons/default_biggrin.png' srcset='/emoticons/biggrin@2x.png 2x' title=':D' width='20' />
Hi Suryanshu,
-len option is available for OptiStruct solver.
I'm attaching a document on 'Increase Computation Speed and Maintain Accuracy' for RADIOSS solver from the Help Menu.
