Modelling laser ablation in COMSOL

Hi,

I have a fairly simple question about COMSOL.

I have made a model in which a block is heated by a pulsing laser heat source.
I am using an iterative approach to solve it by solving for each pulse and then resolving with this solution as the intial conditions.

My question is would it be possilbe to actually 'remove' some of the material from the block, at each iteration, that has a temperature greater than a certain value?
e.g remove individual mesh elements if their temperature is greater than the vaporization temperature of the material.

I would really appreciate some help!
I have 2 weeks left to submit this project and would really like to get this working.

Thanks.
