How to apply the temperature distribution of the Dirichlet boundary?

I'm working on a simulation of thermoelastic wave in a pipe. To reduce the calculation during thermoelastic wave propagation simulation, a partitioning scheme (thermomechanical subregion and mechanical subregion) should be applied.
First, for thermoelastic subregion, a laser pulse has been applied to a microscale model to obtain the temperature distribution profile that arises when the laser pulse of 10mJ energy is shot onto a pipe for 8 ns. Its successfully done and i have no problem to determine the shape of the temperature distribution on the top surface of the model.
Then, instead of applying a heat flux, the temperature distribution curve which is obtained from the above procedure need to be applied to the large scale model to get the radial displacement around the excitation point. The temperature distribution of the Dirichlet boundary should be used. I'm stuck at this stage. Can anyone help me to fix this problem? I don't know how to set the temperature obtained as a boundary for the large scale model.
Please help me. Thank you so much.
