Geometry Addition With Time-Dependent Solving

$

Hello,

Is it possible to vary one dimension of the geometry in a Time-Dependent problem
The process i'm modeling involves injection of material with time and moving heat flux on one its surface along which material is getting deposited with time.

www.comsol.se/community/forums/general/thread/17099/

I tried the methods mentioned in that thread
>Parametric Sweep - Doesn't takes the final solution, starts over from 0 time
>Initialise t=0[s] in the parameters( under Global Definitions node) - doesn't updates the geometry

>Deformed Geometry(dg) - streches the geometry in spatial frame with solutions from previous time frame
>Moving Mesh(ale)- moves the geometry in spatial frame.

Am i missing anything.

Many thanks for any clarification/suggestions.
