I've made sure that my fluent setup is correct, the solid to fluid domains are connected as coupled. but the results are still wrong, for example the heat transfer analysis on Re 500 should get a Nusselt number of 12, but what I get is only 5. is the problem with the meshing such as the inflation layer or some other part? considering that even I have used y+ = 1 but the result is still not valid
