Dear sirs,
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

@Pietro Take a look at the 2nd reference here https://geoxpm.com/publications/, particularly equation (117) for artificial stress (\epsilon_0) and equation (111) for artifical viscosity where ∊ =\eta_q^2
