Thank you Rain, I had already realized how to update soil bulk modulus within my script, implemented in the same way you suggested me. "... # soil bulk modulus set bulkDRY_UPD [expr $EDRY_UPD/(3*(1-2*$nuUPD))] updateMaterials -material 1 bulkModulus $bulkDRY_UPD; ..." And I have also reali...

Dear all, I'm implementing site response analysis simulations. Either quadUP or 9_4quadUP soil elements have been implemented for modeling 1-D analysis. My question regards Opensees plane-strain elements permeability input parameters ($hPerm=kx and $vPerm=ky). Permeability coefficients kx and ky for...

Dear all, I'm implementing site response analysis using PDMY and PDMY02 soil model. I'm using Opensees 2.4.4 Rev.5764. I would like to know which are the references of the last released soil material models and which are the equations implemented in the soil constitutive model defining plastic contr...

Dear all, I'm trying to implement a 1D site effect soil model for cohesionless soils. The question is how to implement an at rest stress initialization for overconsolidated soil column for 2D finite element simulation (quadUP element). To this aim one way is to define initially a fictitious bulk mod...

Dear all, I'm trying to simulate a Direct Simple Shear test simulation with opensees, enforcing drained condition to an isotropically consolidated soil sample. Quad finite element has been used to implement this analysis, and PDMY02 material defines the soil constitutive model properties. The simula...
