Hey.

I'm working with Vista CPD, Turbo Grid and CFX. I created geometry of impeller and volute, than mesh of impeller in TG and mesh of volute in ansys meshing, set settings in CFX-Pre and every time, when I would like to run solution with parallel option I have this error:

Update failed for the Solution component in CFX. The solver failed with a non-zero exit code of: 2

 Details of error:-

 ----------------

 Error detected by routine MAKDAT 

 CDANAM = XMAX CDTYPE = REAL ISIZE = 1048576

 CRESLT = FULL

   Current Directory : /FLOW/MESH/TSTEP0/CLOOP0/ZIF1/SRF_FRAC1

 |        An error has occurred in cfx5solve:         |

 | The ANSYS CFX partitioner exited with return code 1.        |

 +--------------------------------------------------------------------+

That's strange, cuz using serial solution there is no problem with that, but it took too much time. Also when I've not selected Inlet Domain in Five-Edge Vertex Mesh Size Reduction parallel solution started.

Does somebody know any solution of that?

Might be memory allocation related. When in CFX Solver, turn on advanced controls and increase the solver Memory Alloc factors more than 1. (Say 1.2x)

[kacperw201100]

Unfortunately it doesent work

[Amine Ben Hadj Ali]

What did you try? Can you show the head of out-file where the memory has been increased with that factor?

[kacperw201100]

I changed Memory Alloc Factor in partitioner to 1.2. I attached pictures

[Amine Ben Hadj Ali]

Then just increase that factor or just increase under Partitioning Tab the Model Overrides the Real Memory to 20M

[kacperw201100]

It worked! I've changed all factors to 10 and set problem as Large Problem. Thanks!

Great! Happy CFX'ying
