For Conjugate heat transfer simulation, I have 2 solid bodies and 1 fluid domain, my question is should we have to give interface manually or the software itself detects the interface?
My simulation is about generator(Solid 1) produces a heat and passes the heat through fins (Solid 1) attached over the generator surface, fins are cooled with the incoming wind.
I have run 3 different simulation settings but still the solution is getting error. I have used low order scheme and also the adjusted the relaxtion factor but still the error exists.
Requesting you to please look at my file and provide suggestion. Name of the project file is “40fins long domain”
