damping zone and relaxation zone

dong

Hi guys:

@Alex @TPouzol

I have a question about the damping zone in version-4.2 and the relaxation zone in version-4.4.
Are they the same ? Can they both abosorb the wave(an no reflection boundary)?
If not , what is the difference between the two zone?

Regards
