I am trying to create a conjugate heat transfer simulation of a T-Junction pipe flow where hot and cold water mixes. I have been told that there is a way to do this without Syrthes, i.e by using the internal coupling function in Code_Saturne itself. Has anyone successfuly created (or attempted) a simulation of this type on code_saturne and could give help? I have code_saturne 9.0.0 if it matters. Asking here because the Code_Saturne forum pages just seem to be inaccessible. Thanks.
