8. F modeling#

8.1. Characteristics of modeling#

The modeling is D_ PLAN, the contact formulation is DISCRETE, the friction is deactivated.

The contact algorithm used is the one by default.

8.2. Characteristics of the mesh#

8.4. notes#

The results obtained in quadratic without friction with the discrete formulation are identical to those obtained in continuous formulation (modeling B). CALC_PRESSION is used for extrapolated pressures.

In discrete formulation, it is necessary to link the two nodes of the block and the cylinder facing each other initially to prevent the movement of rigid bodies along the \(y\) axis.
