Hello:

Now I have a simulation which has a fluid domain and solid domain. The fluid and solid geometries and mesh are built and generated by Salome. In the coupling of CS and Syrthes, I firstly independently run the fluid and solid simulation, and then click the conjugate heat transfer in CS and Syrthes, and couple the surface of the fluid and solid domain. After that I run the simulation in Code Saturne, and it came out with an Error, can't continue with the computation. The error file in the result folder says:

../../../code_saturne-4.0.6/src/base/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: 0x7f24a8983858 <cs_syr_coupling_all_init+0xe8> (libsaturne.so.0)
2: 0x7f24a88d4e01 <cs_run+0x101> (libsaturne.so.0)

5: 0x400879 <_start+0x29> (cs_solver)
End of stack

And I wonder what's the problem in my simulation. Thanks!

Hello,

Could you post the other information items recommended in this forum ? (meshes are not necessary, the rest may be).

Thanks!

My geometry is a simple one, the fluid domain is in the below with the solid domain above. They share a face which is the top face of the fluid and the bottom face of the solid. The attached files are the solid and fluid geometries and the settings of conjugate heat transfer in code saturne and syrthes.

And also, this is my coupling parameters file. I don't know why I can't upload my case file of code saturne and syrthes, and also the listing file.

And this is my listing file

And this is my case file of Code saturne and Syrthes, just rename them by delete the ".txt", I just found that only file with a suffix can be uploaded in this forum. Thank you!

Hello,

You still did not provide enough info on the setup. Could you provide the Code_Saturne XML file and user subroutines, and the Syrthes logs ?

Hi I think I've run the coupling case in the wrong way by directly click on "run case" on code saturne. Today after I set up the fluid and solid domain and independently run them on CS and Syrthes, I save both case, and execute the "runcase" file. There seems to be some other Errors, this is the screenshot. Thanks.

The Error says that I am lack of a file syrthes4.3.0/arch/x64/lib/libsyrthes_cfd.a, when I click into this directory, I only see a file named libsyrthes_seq, is there some relations between these two files? Thank you again for the help.

Hello,

This is probably an installation issue. At the end of your setup.ini for Syrthes installation, you need both to indicate a path to the PLE library (part of Code_Saturne, which can also be installed alone), and to indicate you want to build the CFD coupling part. Both are near the end of that file, so you should check that.

Yvan
