multiphysics marangoni problem

2) Due to temperature gradient on the surface, Marangoni effect takes place, for
which settings are taken from example model Marangoni convection.
3) Navier-Stokes equations are solved for fluid velocity
4) moving mesh is adjusted accordingly to moving fluid as explained in example
model sloshing tank and others.
Everything works perfectly in two dimensions. I even incorporated ordinary
surface tension there according to yet another example from comsol database.
But I run into serious trouble in three dimensions, where nothing seems to help.
If anyone could explain what is wrong, I'd appreciate it..

I am on the same work, but i have some problems in defining marangoni boundary condition
I did with "test(u)*Tx*gamma" on weak contribution. (and that boundary was on slip boundary condition)
Can you give me an advice?
