Hi all,
I am solving the 2D heat transfer in a rectangular domain(plate). The one side of the plate is subjected to convective BC with h(heat transfer coeff.) changing with time. I have given the sinusoidal profile of h from Define-profile menu in the fluent. The problem with my solution is that after doing transient analysis the heat transfer coeff at that wall is too large. e.g. when i did simulation with h=2000*sin(time) (used in the profile), the result i am getting is around 30000 for the h value.
Any help would be appreciated.

Please check the time steps (use automatic time steps) might be related to your problem...

by change time steps from "fix" to "adaptive" in "run calculation" category then you will need to give end time at setting window...
