Hello together,



I'm trying to set up a steady simulation of a multistage axial turbine using version 2022R1 of ANSYS CFX as part of a student research project. The mesh was given to me and as it is quite large, I try run the setup in parallel.


When I try to run the simulation, the solver gives me following error:

+--------------------------------------------------------------------+
| Checking for Isolated Fluid Regions |
+--------------------------------------------------------------------+
Follower: 22
Follower: 22 Details of error:-
Follower: 22 ----------------
Follower: 22 Error detected by routine LOCDAT
Follower: 22 CDANAM = CRLSND
Follower: 22 CRESLT = NONE
Follower: 22
Follower: 22 Current Directory : /FLOW/SOLVER/PARALLEL/CRL

Parallel run: Received message from follower
--------------------------------------------
Follower partition: 22
Follower routine : ErrAction
Leader location : Message Handler
Message label : 001100279
Message follows below - :

+--------------------------------------------------------------------+
| ERROR #001100279 has occurred in subroutine ErrAction. |
| Message: |
| Stopped in routine MEMERR |
| |
| |
| |
| |
| |
+--------------------------------------------------------------------+

+--------------------------------------------------------------------+
| ERROR #001100279 has occurred in subroutine MESG_RETRIEVE. |
| Message: |
| Stopping the run due to error(s) reported above |
| |
| |
| |
| |
| |
+--------------------------------------------------------------------+

+--------------------------------------------------------------------+
| An error has occurred in cfx5solve: |
| |
| The ANSYS CFX solver exited with return code 1. No results file |
| has been created. |
+--------------------------------------------------------------------+




So I post this with the hope that somebody here in this forum can help me on this problem. The outfile is attached to this post.


Best regards,

The error messages in CFX are not very helpful. I do not know what the problem is here.

Some ideas -
Have you run out of memory? Run it again and check the memory use.
Have you tried running it serial?
Have you tried other parallel approaches? Eg intel vs microsoft MPI if windows, there are other options for linux machines.
Have you tried running it single precision or double precision?

Opaque will become famous soon enough
It is a parallel run error, follower 22 has failed to find a data area named "CRLSND" when "Checking for Isolated Fluid Regions", or else before attempting something else with another banner.

Assuming it is failing in the step the banner indicates, are there any isolated regions? That is, regions of fluids that cannot connect to other fluid regions. Something similar to

Inlet -> Fluid Region 1 | Solid Wall | Fluid Region 2 -> Outlet

Such a setup is not well posed since the condition Inlet and Outlet are not physically connected, or the "pressure boundary condition cannot communicate" from one open boundary to another via a fluid.

Thank you for your answers!


I just had a look at my setup and indeed, CFX made a default boundary for all panels that should have been internal connectivities in the block groups of the single stages. Those default groups are set as walls. Do you know how to change them to internal connectivities?
