Code Error 101

MNMK · September 23, 2024, 10:02

Hi,

I try to simulate the distribution of combustion products inside and outside my car. When I attempt to calculate the model in transient model, I encounter the following error:

I must mention that I do not have any issues when I calculate in steady-state model.
+--------------------------------------------------------------------+
| Buoyancy Reference Information |
+--------------------------------------------------------------------+

Domain Group: CarInside

Buoyancy has been activated. The absolute pressure will include
hydrostatic pressure contribution, using the following reference
coordinates: ( 2.08440E-03,-3.79753E-01,-8.01360E-01).

+--------------------------------------------------------------------+
| An error has occurred in cfx5solve: |
| |
| The ANSYS CFX solver exited with return code 101. No results |
| file has been created. |
+--------------------------------------------------------------------+

End of solution stage.

+--------------------------------------------------------------------+
| The following user files have been saved in the directory |
| /home/simulation/08qeibl7.ea0/CFX_008: |
| |
| pids, mon |
+--------------------------------------------------------------------+

This run of the ANSYS CFX Solver has finished.

How can I fix this error?

wishes,

May I ask which release you are using?

Is it possible for you to run on a more recent release?

If you compare the output files between the steady state output file, and the transient one, can you spot non-obvious differences?

With the available information, I can only advise you to contact the Ansys CFX support line.

Can you please say to me how can I increas the quality of my mesh? +--------------------------------------------------------------------+

What exactly is the meaning of an exclamation mark in mesh statistics?

Hello again,

I found a solution. Normally, I calculate my model through a cluster, but when I calculated it locally on my computer, I saw more errors related to the initialization of my model. When I fixed them, I could calculate the model in transient without any problem.
