Can somebody tell me how to unlock CPU to make simulation faster?
Currently I am using simulation professional. It alway runs at 25% of CPU usage. Can it be faster?
My guess is you have a quad core CPU and are using the iterative solver. My understanding is the iterative solver is not multithreaded and thus does not use other available cores. Try using the direct sparse solver. When run on a single CPU it is slower but it can be multithreaded and run on multiple cores. Whether it is ultimatly faster depends on the problem.
Many thank Peter, You are right. I am using iterative solver, it's alway run at 25% of CPU usage. Anyway I changed the solver to Direct sparse and It has never success for the result. I guess direct sparse is not recommended to use if degree of freedom is higher than 100,000. Am I correct?
DOF does not necessarily control whether or not you should be using the Iterative or Direct Sparse. Yes, with larger DOF problems the Iterative may get results faster but using the Direct Sparse should still get you basically the same results. With today's newer computers 100,000 DOF should not be a problem for the Sparse to solve. Anyway, the point is that you should still be getting results with the Sparse if not a little slower than with the Iterative. Are you saying the analysis will not run to completion when you use the Sparse?
