Hi all,

Dear All,

I hope all feel so fine with your simulations.

Recently, I am simulation a rolling process with a very high dynamic speed (around 5 m/s). Hence, the model is quite dynamic and not Quasi-static.

I use Abaqus Explicit for this simulation. The structure is composite material including several layers with different material properties. In this case, I am using ''Cohesive Surface'' definition as the surface interaction between different layers. 

I have a big problem and there is an error during the simulation process so called:

Dear friends,

I am modeling contact problem with CEL method, which involves 2 kinds of materials (euler-to-euler contact) in euler domain and 3rd material in lagrangian (euler-to-lagrangian contact) domain. The modeling of contact between the euler and lagrangian is okay.

But the modeling of interaction of euler-to-euler contact seems to be lack of information in ABAQUS Documentation.

Does anyone know, how to set up the interaction property of euler-to-euler contact?

How do i add a reinforcement beam to a door of a car at the front using the ls dyna contact card CONSTRAINED_RIGID_BODY ?

Dear everyone,

  I am new to Abaqus and I have been struggling for the past 3 months about this issues I am facing on my modelling...
