Yes I have done that on Ansys Fluent assuming that it would work but the temperature contours developed on the body remains the same irrespective of the number of seconds I set as flow time. And when I import those temperatures on the body in mechanical, only the source times changes while amnalysis time remains the same. This is the reason I am stuck on this simple problem from many days. Below is the first image of steady state analysis, and second image is of transient analysis in which I set the flow time to 2 second. You can see the temperatures on the body are same.
