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.

Hello,
if you change geometry, then you need second model. So model 1 - geometry 1 - study 1 and model 2 - geometry 2 - study 2. You can set the solution of model 1 as initial value for model 2 as follows in two steps:
Study 2 - Values of Dependent Variables:
1) Initial values of variables solved for (Method: Solution, Study: Study 1)
2) Values of variables not solved for (Method: Solution, Study: Study 1)

I hope, that this helps you.
