Discretization
==============


Degrees of freedom
-----------------


.. csv-table::

    "**Modeling**", "**Degrees of freedom (at each vertex node)**"



.. csv-table::

    "3D_ ABSO ", "DX: Next move :math:`X`"
    "", "DY: next move :math:`Y`"
    "", "DZ: next move :math:`Z`"



Support meshes for stiffness matrices
-----------------------------------------

The support meshes of the finite elements can be quadrangles or triangles. The elements are iso-parametric.


.. csv-table::

    "**Modeling**", "**Mesh**", "**Interpolation**", "**Remarks**"



.. csv-table::

    "3D_ ABSO "," TRIA3 ", "linear", ""
    "", "TRIA6 ", "quadratic", ""
    "", "QUAD4 ", "linear", ""
    "", "QUAD8
    QUAD9 ", "quadratic", ""

The same as before.
