You can see in the picture, I have mesh for a fluid , and another mesh for pipe, in the case of the fluid I use Segregated fluid, and for pipe segregated energy because I want to impose heat flux in the wall of the pipe. but I have this error.


Warning: "7" interface type star.common.ContactInterface is incompatible with selected models. Reason: Model SegregatedSolidEnergyModel is incompatible with model(s) on the other side.

I'm wondering why there so many CHT questions right now. And all with nearly the same issue...
May I recommend to carefully read this post:

Your question should already be answered there, bottom of the first page and on the second page. Sorry man, I'm too lazy to type it twice.

Sorry I am beginner in this area!!

my problem, I have only a region(fluid), in this area I have a mesh "generalized cylinde"r and only in specific area of this fluid i used outward extruder (tube), you can see in the picture 1.

for the region fluid I used the model.

"constant Density, gradients, Linear pressure strain two-layer, liquid, reynols stress turbulence, reynolds-averaged navier-stokes, segregaded navier- stokes"

for the region outward extruder (pipe) use the model.

" constant density, Gradients, Segregated solid energy, solid, steady and three dimension"
you can see in the picture 2.

the outward extruder has a heat flux which is programed by field function which depend of the position in the pipe. I know the inlet temperature, inlet pressure and inlet mass fluid. I want to know the distribution the temperaute arround of the pipe.

frist problem. I need the solver of my inlet. exactlyI do not know to obtend this inicial condition temperature.

Second problem. Warning: "7" interface type star.common.ContactInterface is incompatible with selected models. Reason: Model SegregatedSolidEnergyModel is incompatible with model(s) on the other side.

could you help me better?

Well, that was already answer in the post I've linked. The guy there had exactly the same problem with the incompatible models on both sides of the interface.
The solution is quite simple:
Switch on an energy solver IN ALL PHYSICS CONTINUA. You want to simulate heat transfer from the solid to the fluid, but you don't allow the solver to solve the energy equation in the fluid - therefore ccm+ complains about the selected models.

another problem, I had solved the problem of the models for your help, but now I have another error.
