UDSM Interface stiffness from Eoed
Hi all, In the manual it is mentioned that, when using a UDSM, the interface stiffness must be specified by the user in the form of a power law with Eoedref along with UD-pref and UD-Power. How does plaxis utilize this information? Does it use it to assign…

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

error in strain calculation
Hello everyone
I implemented a unified dynamic soil model, but PLAXIS doesn't calculate any strains, and it prints zero (or some times NaN amounts) into a text file. this problem also causes it doesn't draw any plots in soil test section. I'd like to…

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…
Tensile cutoff in UDSM
I am attempting to model a joint between two tunnel sections.
The joint's compressive behaviour can be approximated as a tri-linear elastic. I have created (and tested) a UDSM with tri-linear properties and that seems to works.
However, because the…
