deformed geometry - interface velocity

Hi,
I have a problem (2d-axy) where an interface moves depending on thermal fluxes with a normal velocity of the mesh Vinter.
BUT I have also to impose a mesh velocity Vimposed along an axis on the same boundary.
I cannot find a solution to this problem.
The more accurate solution that I found for the moment is
Prescribed Mesh Velocity:
vr=Vinter*nr
vz=Vinter*nz-Vimposed
with weak constraints
The computation can't start
Some ideas?
Best regards
Julien

It seems that the problem comes from the axis of symetry in 2d axy and the weak constraint condition applied together.
Maybe there is a trick to avoid this problem?
