I am getting Temperature variation in the Cut plot While using User defined material in the Flow Simulation, But in case when i use Flow simulation Pre - defined Material i am not getting temperature variation in the cut plot. Kindly help me to how to get uniform temperature plot in user defined material. For your Reference i enclosed with this mail smaple model with all boundary condition. If i did any mistake please correct me. Thanks in advance.
