Dear CFX Users!

I just started up with CFX a few days ago. So hopefully my problem is easily to be answered.

Just after the memory allocation while running the solver manager the following error-message occurs without any further hint:

Details of error:- ---------------- Error detected by routine MAKDAT CDANAM = CZIF CDTYPE = CHAR ISIZE = 20 CRESLT = OLD

| ERROR #001100279 has occurred in subroutine ErrAction. | Message: stopped in routine MEMERR

Probably someone may help me understanding and solving this error!

Thanks a lot in advance!

Stephan

Hi Stephan,

Try running the simulation again with more memory. You can do that on the solver manager on the advanced tab, put (say) "1.5x" in the memory allocation factor text box. This will increase memory allocation by 1.5 times.

Glenn

Hi Glenn!

Thank you for the quick reply!

Unfortunately after the increased memory allocation (I rised the memory allocation factor for the solver to successively the maximum (9x) means 500MB of total memory for all stacks. All other parameters of the solver manager were taken by default) the error message remains the same...

Is this error message definitely connected to a wrong memory allocation or may there be any shortcoming within my meshes which could lead to such an error?

Best regards

Stephan

Hi Stephan,

I think that if you give a brief description of what you are doing and the code you are using then someone, with a similar experience may help you out.

I had previously received a message that appeared to be a memory problem when actually it was about the license or vise vasa, as well as poor mesh with high aspect ratio or almost zero volume cell. In principle, these errors should be detected at some earlier stage, but at times this does not happen and i do not know why.

Hi Anne

What I am trying to do is to model a onephase mixing vessel with two 4-blade-impellers (Moving-Grid-Problem)

I think it may be the impellers mesh that is to be improved. I am going to do this and will let you know if it lead to any success.

Best Regards

Stephan

Hi Stephan,

Single phase rarely gives memory problems if the mesh is correct. As for memory allocation, I never had to go beyond 1.4x with such type of simulation. You may need to check that number of cell in your domain is what you expected/set.

Best of luck.

anne

Hello again!

You were totally right. The mesh was the Problem: I have got major problems in creating periodicities (in order to crate periodic interfaces for my vessel/impellers) in my mesh builder (CAD2Mesh).

I simplified my Geometry (the Bottom of my Vessel) so that CAD2Mesh could apply periodicities at least for the vessel domain (but still not for my impeller domains).

However, with this modification the model runs and converges but the solver still identifies two isolated Volumes.

Does anyone know how to modify the mesh structure in order to allow the mesh builder to create rotational periodic (means identical) surfaces?

Regards Stephan

Hi Guys,

I faced with this error and I have not any guess about the reason.

I am really hopeful which I could find the reason here with your help.

Additionally I have this message in ANSYS CFX-pre:
"The specified thermal radiation model is enabled for multiphase flow as a beta feature"
I don't know is any relation between this message and that error in cfx-post or not.

I am looking forward to hearing from you

Regards
Marjan

You would have to post the whole output file, or at least enough to put it into context for us to help you.

But if you are using a beta feature then there is no guarantee things will work.

I have the following error
ERROR #001100279 has occurred in subroutine ErrAction Message:
Floating point exception: Overflow

I have a mesh of 6 lacs, initially the same error came up when the courant number exceeded 1. After decreasing the time-step-size the simulation ran but the error sprang up once again and I get the following error along with the previous one

Stopped in routine FPX: C_FPX_HANDLER

I have tried allocating more space but that has failed,
if there is a problem with the mesh, I cant check it because I only have the .def and .res files.

Can anyone help.

I also meet the problem ,can you help me?,how do you solve your problem?

I also met the same problem.This are the information:

what is the reason for the following information “The ANSYS CFX solver exited with return code 1. No results file has been created.”Thank you。

[ghorrocks]

When looking at the output file the most important error is the first error. After that all the following errors are linked to the first error. If you fix the first error then all the other errors generally go away as well. So the first error is the one to focus your attention on. So ignore the final error talking about error code 1.

The first error is an overflow error which is usually caused by numerical instability. The FAQ I linked to describes this in more detail and what to do about it.

Hello everybody.

I have developed a FORTRAN subroutine to use as a junction box in ANSYS-CFX, I compiled the code, but once I tried to run the simulation I get following errors:

+--------------------------------------------------------------------+
| ERROR #001100279 has occurred in subroutine ErrAction. |
| Message: |
| Signal caught: Segmentation violation |
| |
| |

| Message: |

I figured out that those subroutines like USER_GET_TRANS_INFO that contains numerical variables like integer, real ... are not called during the simulation. Is there anybody has any idea bout this problem?

Thank you.

[chenbang]

Hello,eveyone!
I have meet the problem that similar with you,but ,there some different.
If I run it with serial mode,there is no error,but with this mode, it will spend long-time.So ,I use the local parallel.it occures errors,stop in 13 time step.I incredced the memory factor, it still have same problem.The indicate is to reduce the memory usage.but,i don't konw how to do,if anyone konw,please help me! Thank you in advance!

There is an FAQ on overflow errors: https://www.cfd-online.com/Wiki/Ansy...do_about_it.3F

If you get an overflow error in parallel but not in serial that means a partition boundary has lined up with a critical flow feature - that could be a free surface, shock wave or other large gradient area. The simplest fix for this is to use a different partitioning algorithm which moves the partition boundary away from the large gradient area. Change from Metis to recursive bisection or one of the other algorithms.
