D modeling
==============


Characteristics of modeling
-----------------------------------

The modeling is AXIS, the contact formulation is DISCRETE, only the frictionless case is treated. A discrete 2D_ DIS_T element makes it possible to block rigid body movements.

The contact is processed with the projected conjugate gradient algorithm GCP.


Characteristics of the mesh
----------------------------

notes
---------

The results on a quadratic mesh change very little compared to C modeling (linear mesh). They are still just as close to the references.
