B modeling
==============


Characteristics of modeling
-----------------------------------

The finite elements affected on the mesh cells are those from the D_ PLAN, COQUE_AXIS, 3D and POU_D_E models.


* 2D nodes have degrees of freedom :math:`\mathrm{DX}`, :math:`\mathrm{DY}`

(+ :math:`\mathrm{DRZ}` for :math:`B` and :math:`\mathrm{E1}`),


* 3D knots have degrees of freedom :math:`\mathrm{DX}`, :math:`\mathrm{DY}`, :math:`\mathrm{DZ}`

(+ :math:`\mathrm{DRX}`, :math:`\mathrm{DRY}`, :math:`\mathrm{DRZ}` for :math:`I`, :math:`N`, and :math:`\mathrm{Q1}`).


Characteristics of the mesh
