I want to simulate with the passive absorption function using sponge layers. But I don't know the meaning of the following parameters in CasePistonDamping_REG:

Sorry for not explaining this properly. We are now working on XML_v4.2_GUIDE.pdf where this will be indicated.

redumax=beta in Eq.46 in section 3.10.1 of the Users Guide redumax=10 (that is the suggested value, value as default)

Note that you have to create a damping zone of at least one wavelength (L) x1= is the maximum x of the damping zone x0= is the initial x of the damping zone

overlimit=1 adds extra space (1 meter in x) where velocity of the particles fall down to zero
