Code_Saturne/Syrthes coupling

[andrea28]

Hello,
I am running a coupled simulation, I made the simulation for the fluid and the solid separately and now I'm trying to couple them, but I get the following error in the fluid directory:
cs_syr_coupling.c:937: Fatal error.

At least 1 SYRTHES coupling was defined for which
no communication with a SYRTHES instance is possible.


Call stack:
1: 0x7fcb7252ece5 <cs_syr_coupling_all_init+0xb05> (libsaturne.so.0)
2: 0x7fcb72469b2b <cs_run+0xfb> (libsaturne.so.0)
3: 0x7fcb72469922 <main+0x112> (libsaturne.so.0)
4: 0x7fcb6fbeeb15 <__libc_start_main+0xf5> (libc.so.6)
5: 0x4008e9 <> (cs_solver)
End of stack

Any idea?

Regards,

Andrea

Hello,

It seems you defined multiple couplings, both named SOLID, while you only have one coupled Syrthes computation. You probably need to define only one coupling in the Code_Saturne GUI (use "and" to combine your selection criteria). In case of multiple couplings, the name becomes important, as it must match the Syrthes subdirectory (case) name.

So I have 2 surfaces interested by the conjugate heat transfer:
-in CS GUI I put in the "selection criteria" "8 and 6"
-in SYRTHES in the "References" "16 13"
Is that correct?
I want that 8 interacts with 16 and 6 with 13.

Hello,

Yes, interaction only occurs for surfaces "in contact" (or very close), so "and" should work fine here.

Hello,
I managed to create 2 different directory for Syrthes cases, with different names. Everything seems to work but in practice the calculation doesn't start. From the listing I see that CS tries to create 3 couplings but I put there only two.
I attached the listing and the routine I am using.

Hello,

Do you also have any definitions using the GUI ? This might lead to multiple definitions.

Thanks!!!
Now it works just fine.
