Hi everyone,
I’m SM Shawaz Khaled, an MSc student currently working with GiD + OpenSees for dynamic soil–structure interaction modeling.
I’m having persistent trouble running the PressureDependentMultiYield02 (PDMY02) constitutive model. I’m quite comfortable with the ElasticIsotropic model — it runs smoothly — but as soon as I switch to PDMY02, the analysis fails immediately, even for a simple gravity load case.
Could anyone please guide me with the exact workflow or step-by-step process to get the PDMY02 model running properly in GiD/OpenSees?
Any help or working example would be greatly appreciated!
Thanks in advance
