Hello,

I am trying to simulate a flow of water through an externally heated pipe with a porous core. Since I am interested in the temperature distribution in both solid and fluid domains, I am analyzing both of them in Fluent. Here is the model as shown in Mechanical block:

Can you show the cell zones conditions?n

Here they are: nFluid domains are numbered 1 to 5, 1 being the inlet coreless section and 5 the outlet coreless section as shown on the first image on the last post. n

Can you just change the names of the boundaries to something like interior_1 and interior_2 before reading the mesh into Fluent?n

It's because you used a special label in the model. Inlet, outlet, outflow, symmetry and some others force the solver to set a certain boundary type. It is fixable in Fluent, but not without some TUI commands and knowledge of the solver. As suggests alter the named selection in Meshing and it'll come through OK. n

Indeed, I changed the names to Interior 1 and 2 and the problem got solved. Thank you a lot! n
