Defining of initial temperature of certain body in unsteady heat transfer problem

toodrunktorun · September 5, 2013, 10:08

The question I'm asking seems to be simple one and I'm sorry if it has been already discussed in this forum.

The problem is the following. There are two bodies A and B which are in a thermal contact. Body A has a constant temperature T_A=T0, as for another one its temperature is equal to T_B(t=0) for the initial moment of time. Using energy equation in Ansys Fluent I have to calculate temperature profile in body B for t>0. In other words T_B(t>0)=? I know how to define a constant temperature in Ansys Fluent but I don't succeed in initial temperature defining. Could you please explain me how to do that. Thank you.
