Hello
I am trying to simulate flow for a Pelton runner. I have two fluid domains: one is stationary and the other is rotating. There are no errors till the CFX Pre stage. I am using Ansys 13 cfx on Intel Core i5-2400 3.10 ghz quadcore processor with 16gb of ram. I am getting the following error when using the CFX solver manager: Run mode: serial run Host computer: RENP-PC (PID:3424) Job started: Wed Jan 02 14:25:18 2013 +--------------------------------------------------------------------+ | Memory Allocated for Run (Actual usage may be less) | +--------------------------------------------------------------------+ Data Type Kwords Words/Node Words/Elem Kbytes Bytes/Node Real 5497120.0 606.29 121.26 21473124.0 2425.17 Integer 1215248.6 134.03 26.81 4747064.5 536.13 Character 3799.5 0.42 0.08 3710.5 0.42 Logical 80.0 0.01 0.00 312.5 0.04 Double 1208.0 0.13 0.03 9437.5 1.07 +--------------------------------------------------------------------+ | ERROR #001100279 has occurred in subroutine ErrAction. | | Message: | | The total number of words needed for the Real stack exceeds the m- | | aximum supported by the flow solver: 2,147,483,647.

Going to 2 partitions has reduced the real stack size from 5.5GB to 2.8GB. The answer should be obvious - you need at least 3 partitions for this to run, then the partitions will be under the 2.1GB limit.

Thank you mate. That did the trick but i had to reduce to the number of nodes too.
So the main idea is increasing the number of partitions if there is stack overflow? CHEERS!!! |

The point is you were running out of memory, so either you need more memory per processor or you need to reduce memory useage per processor. One way to do this is to use more partitions since this distributes storage over the partitions making the useage per processor less so you don't run out of memory.

You can use as many partitions as you have licenses for. But note that simulation speed will reduce if you have too many partitions, and licenses cost money so the value for money equation is more restrictive again.

Are you using 64 bit CFX on a 64 bit OS? You need to do this for large models.

Have you read the error message? It says "If the standard partitioner runs out of memory you will need to run the large problem partitioner." Doesn't it tell you exactly what to do?
Also note that for large simulations you need to be running 64 bit CFX on a 64 bit OS. |
