Level set capillary filling

Hi,
I'm trying to run the level set capillary filling library model using COMSOL 4.1.112. I simple do not understand how to set up the solvers (using transient initialization). In COMSOL 3.5 (which the model was developed for), the same task is rather easy and works well.
I tried to set a first study step the does the transient initialization. This seems to work fine. Then, a second study step that solves the time dependent problem. This fails, giving "Failed to find consistent initial values.
Out of memory during LU factorization. Last time step is not converged."

Hi
Adding in several solvers and linking them is nice in v4.1 (but I agree it took me some time to understand the logic) then once that understood,, it becomes rather easy.
You could take a structural "buckling" example as there COMSOL generates the 2 studies; stationary + eigenfrequency process nicely, with an intermediate store solution AND the stored solution initial time step set-up

Good luck
