However, I could not find any input regarding the water whether it is the saturation or the effect into soil (ex: seepage, permeability)

I'm having some doubts about some parameters governing the SPH setting. In particular, I'm not finding on the manual the meaning of both "EPs coefficient, artificial stress" and "Eta coefficient, artificial viscosity". In which equations they appear?

Moreover, I would like to know if it is possible in some way to set a damping coefficient in the analyses.

I look forward to your reply.

Best regards

Pietro
