Hello
I want to model a cylindrical steel silo under earthquake excitation. I have modeled bulk material inside silo with drucker-prager model, I have used 8 node solid elements for modeling of materials inside silo and 4 node shell elements for modeling of silo walls and silo bottom. I have...
hello
I want to model granular material under cyclic loading and I want to use vumat in abaqus explicit. I have download a umat from www.soilmodels.info and I want to convert it to vumat. can any one help me. because I do not have enough expertise to do this work.

because when I use tie constraint I will encounter overconstraint problem due to my model has surface to surface contact and accelaration boundray conditions too
I have an discrete rigid orphan mesh and a deformable body orphan mesh that have coincident nodes I want to merge these nodes without converting these parts to a discrete rigid part what should I do?
Please guide me.
now my model have only two parts. I have used drucker prager model instead of umat before for modeling of granular material and these warnings still exist.
I want to model a steel silo under earthquake excitation.
I used a umat subroutine for constitutive behavior of granular material (hypoplastic mateial with inergranular strain) I tried to model a steel silo with granular material under earthquake excitation with Abaqus standard. I modeled silo...
