   I'm working right now on my bechelor thesis which is about cooling the turbine blade with new innovative mechanisms, i'm setting up a currently this blade with cooling passages to investigate the blade when only cooling passages and film cooling holes are only used as cooling mechanisms. later on i will be adding the new techniques which will be used in the blade, but in the scenario where only cooling passages and film cooling holes are only used the solution never proceeds and it stays as seen in the following picture 

what can be the reason for the incorrect setup in this case ?
the modes that are used are viscous k-e and momentum  for the simplicity at the beginning
boundary conditions are inlet and outlets for the gas from the gas domain
inlet from a single cooling passage hole from the bottom and outlets which will be multiple outlets going out from the film cooling holes and the the final cooling passage in the bottom of the tail 
walls and symmetry have been also defined for the blade and the domain 
but the solution is still not proceeding

Hi Abod,

Although it will be difficult to comment with available information, here is the reference which will help you with setting up a CHT simulation.

ANSYS Fluent Student: Conjugate Heat Transfer in a Heat Sink - Ansys Knowledge

Additionally, you can perform following steps before starting the simulation:

1. Perform mesh check and Check case,
2. Make sure the boundary conditions applied are not conflicting.
