Execution Time after few iterations very high
I have a question to you. After starting my simulation (~700.000 cells on 10 cores : ~ 70.000 cells per core) the execution time of the first 6 iterations is round about 4 seconds. After that the execution time goes to very high values.
Is that normal? Depends on the cores (too many?)?
Does anyone has some advices?
Are you certain this is a parallel related problem? Doesn't this behavior occur when running in serial?
From your description, it's very hard to assess the reason why this might be happening. It could be due to:
thanks for your replay. I have no experience in - how many cores are good for a cfd calculation - that the cores are working good and dont transfer data to each of them.
In that case I think its not a parallel problem :)
But thanks for your replay. I was just wondering why it is so.
Maybe it is the fact, that I start from a solution and mapped it to the new mesh (extended mesh).
