Setting up a previously solved physics as an initial condition for a second physics

I am new to COMSOL 4.3a and I have what seems to be a simple dilemma, but I can't figure it out.
I have a model incorporating three different physics. I want to run COMSOL to solve for the first physics, then use results from the first physics to solve for the second and then third physics. However, I don't want to run the first physics over and over again, because I am not changing any parameters in physics 1 (and physics #1 is not dependent on #2 or 3). I am changing variables in physics 2 and 3, and want to see what effect those changes have on my results. I would like to do this to save computational time, because I now have the program set up to where I am solving all three physics every time when the first physics is never changing. So can anybody tell me how can I solve for physics 1 only once, and use those results as initial conditions for physics 2 and 3?

Hello!
You can solve your first physic in a first study; add a second study with your second physic.
In this second study you can set up, that you want to use the solution from first study.
