Junction point movement of moving boundary (or corrosion) problem

Dear COMSOL community and viewers, - I was hoping you could provide a clear concept to help with the topic below.
I am working on the numerical simulation of a pitting corrosion process. Essentially we solve a Moving Boundary problem in a domain. The solution on a portion of the boundary of the domain then gives a normal velocity for that portion. Essentially to define the direction of movement at each node we use vertex normal vectors, but there are some issues with the movement of the “corners” (the transition point between moving and non-moving portions of the boundary) of the moving boundary.
My questions are as follows:
- How does COMSOL work for the transition or junction point movement?
Does COMSOL use any normal velocity (or any other techniques) at the junction point movement?
What kind of a front tracking algorithm uses in COMSOL?
Is it possible to solve this issue using COMSOL? How?
Advance thanks for suggestion and opinion!.
