Hey again, I changed the names of the fluid cases and now syrthes can read the 2 surfaces. However, it stops after the 1st iteration and gives this error in syrthes.log file : [chausson:27801] *** Process received signal *** [chausson:27801] Signal: Segmentation fault (11) [chausson:27801] Signal co...

Yes, the second fluid listing gives this error :
SYRTHES coupling 0: initializing MPI communication ... SIGTERM signal (termination) received.
--> computation interrupted by environment.
Syrthes can't read the second coupling I think but I can't figure out why?

Hello again, I got some news, I now get this new error message but I still don't know how to get through it: [chausson:10825] *** An error occurred in MPI_Allreduce [chausson:10825] *** reported by process [47672487641089,47669842018304] [chausson:10825] *** on communicator MPI_COMM_WORLD [chausson:...

Hello,
I am trying to run a parallel calculation with 2 processors on Syrthes but the preprocessing seems to stop in this step:

*** CREE_TABLES_PARALL : creation of temporary tables for parallel execution

Does anyone know what to do to make this work?
Any help would be very appreciated.

Hello,
Are there any news please?

Hello, I am running a coupling calculation between Neptune and Syrthes and I need to have a time varying time step in Neptune so I tried the automatic time step of Syrthes but I have no idea what to put in the maximum temperature variation while I can't know how much the temperature of the solid wil...

Hello,
here are the fluid listings and the coupling parameters file.
thank you for your help.

Hello,
Thank you for your reply.
Here are the files of neptune and syrthes.
The extension .syd is not allowed so I attached the file with the extension .odt
Thank you for your help.

I actually think that the problem is with the 2 fluid domains not with syrthes, but I still can't figure out how to get through it?

Yes, I defined 2 couplings with Neptune_cfd with 2 different references but it doesn't work. It still reads only one coupling in the syrthes.log file.
