coupled eulerian lagrangian

Hi there,

 Has anyone ever used a vumat subroutine with Eulerian elements? it seems that the stress update formulation is different from the way it is in Lagrangian approach! If you have any experience in this regard I'd highly appreciate if you share it with me.

 thanks

I am trying to model a tube which is filled with liquid that is being crushed.  I am using Coupled Eulerian Lagrangian to model the problem in abaqus, and there are a few distortions/errors in the model.  I am using symmetry to model only quarter of the model.  The liquid actually comes out from the sides of the tubes as the two attached pictures show.
