tracking volume change with time

Hi, as the title suggests, I'd like to plot the volume of a domain in my model with respect to time. I'm using comsol 3.5. Does anyone know if it can it do this? and, if so, how?
Thanks,
Em

Hi
which physics/application mode are you using ?
if you are in structural, I would try to :
turn on the deformed frame in the physics tab and then integrate the domain in the deformed frame. The volume is the integration of operand "1" ( times implicit dx*dy*dz) but if you integrate the material frame it is the underformed volume, you need to integrate x=X+u,y=Y+v,z=Z+w
if you arenot in the structural, then I'm not sure how you define the "change in volume" it becomes module dependent, no ?

Good luck
