Coordinates of the points:

Characteristics of the elements:

Mesh types:

24 COQUE_3D

24 TRIA7

Boundary conditions:

Mesh group \(\mathrm{AB}\):

  1. movement along the Y axis: DY = 0

  2. rotation around the X axis: DRX = 0

  3. rotation around the Z axis: DRZ = 0

Mesh group \(\mathrm{CD}\):

  1. movement along the X axis: DX = 0

  2. rotation around the Y axis: DRY = 0

  3. rotation around the Z axis: DRZ = 0

Node group \(\mathrm{PB}\):

  1. movement along the Z axis: DZ = 0

with \(\mathrm{AB}\) the group of elements connecting \(\mathrm{PA}\) and \(\mathrm{PB}\)

and \(\mathrm{CD}\) the one connecting \(\mathrm{PC}\) and \(\mathrm{PD}\)

3.2. Tested sizes and results#

Systematically, we take the values of the displacements and the constraints on the node \(\mathrm{PA}\)
