Lode angle dependence

Dear all,

I was wondering whether a (new) constitutive model is available (or will be available in the next future) accounting for soil liquefaction simulation capabilities and including also a dependence from the third invariant of the deviatoric stress tensor.

Thank you,

Handling "Transformation" Constraints

Dear all, I've been working in the past few days on a 2D numerical model of a submerged slope. I began from the very useful example problem available within the OPENSEES documentation ("Dynamic Effective Stress Analysis of a Slope"). However, in that problem fixed null values are assigned to pore pr...

Displacements re-initialisation following geostatic step

Dear all,

this is to ask you about the best/fastest way in OPENSEES to reset the displacements field obtained as a result of a geostatic step, prior to move to the subsequent analysis stages.

Thank you,

Hydraulic boundary conditions

Dear all, I've been studying/using OPENSEES in the past few weeks, with the intention of performing a dynamic analysis of a 2D model of a submerged slope. I found OPENSEES a very powerful tool for this purpose. In addition, the example contained in the "Example Manual" is very similar to my case and...
