Dear all

I am trying to solve the problem of heat transfer from turbine rotor to cooling flow coming from compressor. So inlet is the cooling air and outlet is the air to turbine section. please refer to second Fig.

I have defined the boundary conditions as shown in Fig. 2 and defined them in ICEM BC panel as shown in Fig. 3.

My problem is that we I open this mesh file into fluent I only get the axis, rotor (wall), stator (wall) and stator shroud (wall) boundary conditions in Fluent. I tried many times but I am unable to get the inlet, outlet and rotor shroud boundary conditions in Fluent.

Any suggestion ?
