Hello,
I am working on a model on which the surface position is changing according to this equation:
n · v = n · ∇c
where
( c ) is a dependent variable known over the surface
( v ) is The time derivative of the surface position
( n ) is The unit vector pointing in the normal direction of
the surface
How I can define this equation to comsol

thanks
