Boundary conditions:

Mesh group :math:`\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 :math:`\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 :math:`\mathrm{PB}`:


1. movement along the Z axis: DZ = 0

with :math:`\mathrm{AB}` the group of elements connecting :math:`\mathrm{PA}` and :math:`\mathrm{PB}`

and :math:`\mathrm{CD}` the one connecting :math:`\mathrm{PC}` and :math:`\mathrm{PD}`
