How to use solution as initial value for 2nd study with changed geometry?

Hello Everybody. I’m using comsol 4.3a.

I try to use the solution from study 1 (stationary heat transfer) as the initial temperature value for a second time dependent study. Further a new geometry interval with new initial value and BC has to be added to the model for to the second study.

Can anybody give me some help to realize that? Thanks a lot in advance.
