Hi all,

I have just upgraded from R14.5.7 to R15.0.
When I'm running simulations that previously were running fine in the old version, I am now receiving this message:

Node 0: Process xxxx: Received signal SIGSEGV
(xxxx) being different from run to run.

directly followed by:

MPI Application rank 1 exited before MPI_Finalize() with status 2
The fl process could not be started.

Any ideas?

Best regards,

Joakim

I have exactly the same problem. Did you manage to solve this?

vasava will become famous soon enough
Do both the versions have parallel capabilities?

You need to install the version of MPI for Ansys 15.0. See C:\Program Files\ANSYS Inc\v150\commonfiles\MPI\Platform\Windows\9.1\INST ALL_Platform-MPI_README.docx

This error went away for me when I disabled DPM physical models, then re-enabled them.

Did you just unclick "interaction with contineous phase" in the DPM panel and immediately select it again? Because I can't get it to work.

For me I had Particle radiation and thermophoretic force selected in the physical models tab. I disabled these and then ran the DPM one time using the Particle track results. Then I turned them back on and the error went away.

After clicking save the error seemed to come back. So after a bit of experimentation I found it only happened when i had thermophoretic force selected. Fortunately this wasn't essential so I'm not using this one anymore and it works fine now.

Great, just de-selecting the thermophoretic force works. Thanks a lot, I will write Ansys a ticket.

ANSYS replies:

"This appears to be a bug in the software. It has been logged for fixing in the next release

As a workaround you can switch to polynomial formulation instead of Talbot, then it works fine."

Is this related to using the thermophoresis model? Which version of Fluent are you using? If it's 15.0, have you tried installing the 15.0.7 update?

Hi anthony05 ; i am using DPM+VOF and just drag force is activated , i don't know about "thermophoresis model'' ( I'm using 15.0.0 , i think i should try the update , i wish it works , how did you solve your own problem , was it the same as mine ? thank for reply

I found what the problem was by turning off models one by one until the problem disappeared.

Thermophoresis is part of the Dpm model and is found under Discrete Phase>Physical models> Thermophoretic force

I haven't installed the 15.0.7 update so I'm not sure if this fixes it.

I wrote a udf to account for breakup and coalescence in bubble plume modelling , the macro is : ''DEFINE_EXECUTE_AT_END(Remove_and_write_to_file)' ' in udf the calculation on dpm is done and at the end i want to write data on a text file (data about position and mass of particles) , i used ''udm'' in code to save data during calculation and i wrote my code for parallel proccesing(the transferring data betweeon cores is considered) , but at the end of first time step fluent stops and this error occurs , i am running my model on my lap top lenovo z500 corei7 , in one forum i read this happend because cores can not find eachother , i don't know where this error come from and how to solve :

According to quote #4 i installed : the version of MPI for Ansys 15.0. See C:\Program Files\ANSYS Inc\v150\commonfiles\MPI\Platform\Windows\9.1\INST ALL_Platform-MPI_README.docx
but it does not work either

It sound's like it is unrelated to the problem I was having. I'm not to familiar with parallel UDFs. Perhaps it would be better to post this in a new thread in the Fluent UDF sub-forum.

Did you initialize the UDM under user-defined?
Errors like this are typically a result of wrong memory management, for example writing to a variable that has not been allocated.
