20 shell elements DKQ

2 POU_D_E beam elements

There is a game (:math:`0.2\mathit{mm}`) between points :math:`H` and :math:`D` in the mesh.

A fictional game (:math:`0.2\mathit{mm}`) is introduced between the points :math:`F` and :math:`C` by the keyword DIST_ESCL of DEFI_CONTACT with FORMULATION =' DISCRETE '.

The contact is processed between the POI1 mesh using the ESCL_FIXE keyword from DEFI_CONTACT.


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

Number of knots: 46

Number of meshes and types: 20 QUAD4, 2 SEG2
