PM4Sand model - manual setting of the parameter h0
Good morning,
Is it possible to set manually the value of the parameter h0 for the PM4Sand model?
The value is computed internally with equation 2.31 of the PM4Sand model manual.
Thank you in advance,
Andrea Balia
UDSM for Interfaces
Dear Plaxis/Bentley community,
we are working on soil-geogrid interaction and want to apply user-defined properties to the interface via a UDSM. The overall goal is to update the shear stiffness of the interface elements in each calculation step depending…
