Hi,

I am trying to add temperature field to channel flow simulations. So, firstly I have started with channel395 tutorial case. This test case is using cyclic boundary condition, which is not fine for temperature field, because I want to have at the inlet constant temperature. I found this solution:

inlet
{
type inletOutlet;
patchType cyclic;
inletValue uniform 303.15;
value uniform 303.15;
}

but, this does not work for me, as I get the following error:

inconsistent patch and patchField types for
patch type cyclic and patchField type inletOutlet

.
I tried using mapping boundary condition, but here I get another problem, because I cannot get turbulent flow when using mapped boundary condition. Even if I start the simulation with mapped boundary condition, the turbulence dies down over time and I cannot see, where the problem is. I tried using mapped boundary condition before with different cases and it worked fine.
Does anyone have any solutions to these two problems? Thanks!
