hi everybody.
i used FLUENT to do FSI under the situation of steady, the model is consisted of two parts, inner and outer. the inner is fluid, outer is solid. heat transfer is considered in FSI, because of i want to know the difference of the fluid between inlet and oulet. i choose the COUPLED for wall-shadow and wall. use udf to apply B.C to solid's faces. at the end of the simulation, read the result. there is no difference between inlet and outlet. the heat transfermation only occur at the neary of boundary between solid and fluid.

i am really got headache under the circumstance as this. i do want to know what happened. pls, help me. thank you very much for your help.
