CFX pre error in assigning material to the domains

madan · February 18, 2015, 02:10

Hello,
I am doing a numerical simulation in CFX about the turbine nozzle blade, where I am using a cooling passage inside the blade periphery. The cooling method is rib-turbulated cooling for the turbine blade. But I am getting the problem while assigning the material for the domains in CFX-pre. I have two domains namely Gas and Coolant. The gas domain which has the material properties of ideal gas at 1200 K and the coolant domain has the material properties of ideal gas at 700 K. I have created two materials separately and tried to assign the material for the domains. If I assign gas for a domain the same is getting assigned for the another domain. For eg, If I assign gas as the material for the Gas domain it is getting automatically assigned for the Coolant domain also. Even though if I am changing the material for the another(Coolant) domain it affects the current(Gas) domain also. Please help me out from this problem. I am new to simulation field so I am not that much familiar with all the options in CFX. I am using CFX 5 for the simulation of the problem

Thanks,

Regards,

Madan
