Dear community,

I want to simulate a lab experiment of thermal properties of geomaterials around pipe heat exchangers. I am reproducing the geometry with a layered mesh starting from a section of the sample perpendicular to the pipes axis.

I have 10 parallel pipes and i need to "connect" them in series.

So i need the fluid that exits the model at the "end" of the first pipe (through a 2nd kind BC) enters again in the model at the "beginning" of the second pipe (having the same temperature at the exit from the first pipe) and so on...

Does anyone know how to do that?
