Hi guys,

I was wondering if anyone can help me, i get the following error code when trying to run my simulation in CFX:

'update failed for the Solution componen in Fluid Flow (CFX). The solver failed with a non-zero exit code of: 2'

With the following infromation in the details section:

I cant find any information on it anywhere, and as a very novice user of ANSYS, I dont really understand what it means. I went to see my professor at uni and he hadnt seen it before either. I was wondering if anyone could be of assistance?

Cheers!

What does the solver output file say? That usually shows a much clearer error message, and is usually is more helpful than the details, which are very verbose.

[KUAlex]

This is the message from the solver:

Error interpolating results onto the new mesh: C:\Program |
| Files\ANSYS Inc\v150\CFX\bin\winnt-amd64\solver-pcmpi.exe exited |
| with return code 1.

[ghorrocks]

So now you have something to target - it is the interpolation of results step. But we cannot tell what based on the sketchy information you have provided so far.

Hi people, I have a similar error finished with 1 and 2 but maybe because other reasons not talked before:

ERROR #002100011 has occurred in subroutine cVolSec.

Message: A negative SECTOR volume has been detected. Execution will proceed
but this is a possible cause of robustness problems.
The location of the first negative volume is reported below.
Volume : -0.1542E-16
Location : ( 0.34000E+00, -0.38993E+02, 0.44832E+02)
This warning may be made fatal by setting the expert parameter
'negative volume option = 1'.

ERROR #001100279 has occurred in subroutine ErrAction.

Message: Floating point exception: Invalid number

ERROR #001100279 has occurred in subroutine ErrAction.

Message: Stopped in routine FPX: C_FPX_HANDLER

I have different geometries inside the problem to solve: When I apply interface boundary condition between a curved volume of fluid and a curved volume of solid I get this error. When I say to CFX that they are just walls the solver runs. Maybe it is a problem of the mesh but It is quite smooth. Any help please?? Thank you!

[ghorrocks]

If you got this because of a moving mesh simulation: This is an FAQ: http://www.cfd-online.com/Wiki/Ansys..._went_wrong.3F

If you got this otherwise: In ICEM if you smooth a mesh too much you can turn some elements inside out. You will have to remesh it in ICEM, but make sure you do not smooth the mesh too much again.

[Vortice]

Thank you ghorrocks, It is a static mesh. I tried with a coarser mesh, more automatic and not so tunned by me and now it works. The point is I didn't understand why that happened but with your answer I guess I found the solution :-)

ERROR #333100220 has occurred in subroutine Out_Memory. |
| Message: |
| |
| The allocated memory exceeds the system memory on 1 host(s). |

| The logical expert parameter "enforce system memory limit" |

| |
| The current setting is: fatal |

| Allocating more than the system memory may result in slow or |

[ghorrocks]

No it is not the same error. Your problem is simply you have run out of memory in your workstation. You can either:

* Get more memory
* Use distributed parallel to share it across several workstations
* Make the simulation smaller
* Buy some time on cloud computing like AWS to run it

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

how can ı solve that porblem ?? it so emergency

[ghorrocks]

how can ı solve that porblem ?

No idea. You better explain what you are doing and where the error message occurs before we can help you.

it so emergency

Is that right? Well, then you better contact the CFD emergency services then.

Here on the forum we are all volunteers and we help people when we can. If you need urgent help talk to ANSYS Support as that is what you pay them for.

okey. please tell me. how can ı solve

[ghorrocks]

Have you read the message? It tells you exactly what the problem is. It could not find a license.

Also: Please do not post duplicate posts on multiple threads. Just post a question once. I have deleted the duplicate posts.

[morvinn]

look. ı can understand you. you told it is not found licence. but ı have stundent licence. okey. no problem until here. now how can ı solve that problem ?

[ghorrocks]

Check that your license server is working. Can you run a tutorial example?

Be aware that the student version has restrictions. I think there is a maximum number of nodes it can handle. Check your model does not have more than the maximum number of nodes.

Hi,

I am doing pressure loss calculation of a valve in CFX and getting an error in the output file as

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

End of solution stage.


Can anyone help me to fix this?... Thank You.

[ghorrocks]

You cannot debug CFX error messages from the error code alone. You need to read it in context of what you are doing.

Please post your output file and an image of what you are doing. And as this has nothing to do with the rest of this thread please start a new thread for a new question.

Thanks I have posted a new thread.

I encountered this problem and solved it
The solution is that the interfering surface must be completely adherent to the other surface
If it is a rotating part, for example a wind turbine, any opening in which there are elements and nodes connected to the rotating part must be closed
