6. D modeling#

6.1. 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.

6.2. Characteristics of the mesh#

Number of knots: 2155

Number of meshes and types: 671 QUAD8.

6.4. 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.
