Good Luck,

P.S: For the future, I strongly suggest that you first search for the key words of your problem in the posted messages and if there are no related messages then you could try posting a new message. That way we would keep the forum more organized.

Hi,

This is briefly what I know about SSI (Soil-structure-interaction):

Kinematic SSI ==> Assign mass to the structure, assign mass to the PDMY, don't assign mass to soil quad elements.

Inertial SSI ==> Assign mass to the structure, assign mass to the PDMY, assign mass to soil quad elements. That way your soil and structure will have a lumped mass matrix.

I hope this helps,

as I know:

kinematic SSI: mass density and stiffness of soil present, stiffness of structure present but mass of structure does not present. Is it true?

please see this my post:
