Re: Conjugate heat transfer of simple geometries - comparison with exp data

Hello Antech, Thank you again for your help. It works now. The variable zoneTempAve output gives temperature in degC. I have a difference of 2 - 3 degC when I compare with the integration of Paraview. I need to check if the time is the same when I measure the average temperature. Is it possible to s...

Re: Conjugate heat transfert - 2D - Flow past cylinder

Hello,

Here is the 2 meshes of the fluid and solid parts if someone wants to try the joining and coupling.

Best regards

Re: Conjugate heat transfer of simple geometries - comparison with exp data

Yes it is good now, no more error during compilation! I don't know how to extract the value now. I try also fprint but everything returns errors... cs_post_write_var(mesh_id, CS_POST_WRITER_ALL_ASSOCIATED, /* writer id filter */ "zoneTempAve", /* var_name */ 1, /* var_dim */ true, /* inter...

Re: Conjugate heat transfer of simple geometries - comparison with exp data

Hello Antech, Thank you for your help. I think it is really close to work. The compiler complains about /home/julien/Travail/test_cyl4/SRC/cs_user_extra_operations.c:104:25: error: ‘cellVlm’ undeclared (first use in this function) 104 | zoneVlmSum=zoneVlmSum+cellVlm[iCell]; /* Zone volume sum */ | ^...

Re: Conjugate heat transfer of simple geometries - comparison with exp data

Hello Antech, Yes in my case z is related to volume of the "solid" zone I don't understand where is the link between z defined below const cs_zone_t *z = cs_volume_zone_by_name("solid"); for (cs_lnum_t idx = 0 ; idx < z->n_elts; ii++) { cs_lnum_t ii = z->elt_ids[idx]; temptot += ...

Re: Conjugate heat transfert - 2D - Flow past cylinder

If I remove from the list of BC one of the two interface BC.

I have a new error message about wall distance.

Re: Conjugate heat transfert - 2D - Flow past cylinder

Hello,

With the join definition syntax:
interface_fs or interface_sl

the join is done but a new problem appears.
Again with some interface definition, see the solver log file

Best regards

Re: Conjugate heat transfer of simple geometries - comparison with exp data

Hello Yvan, Thank you for your answer. I modify my file. I have a lot of warnings. First I try to make it works in serial. There is the modified code /*============================================================================ * This function is called at the end of each time step, and has a very ...

Re: Conjugate heat transfert - 2D - Flow past cylinder

Hello, With the syntax 'interface_fs' OR 'interface_sf' or without the punctuation interface_fs OR interface_sf gives exactly the same result. Maybe my boundary declaration is not appropriate, I have 2 boundaries for the interface solid/ fluid? Maybe someone has already define a simple case of CHT w...
