Discretization

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


.. csv-table::

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



.. csv-table::

    "AXIS, AXIS_DIAG, PLAN, PLAN_DIAG "," TEMP: corresponds to the temperature"



Support mesh for stiffness matrices
------------------------

The support cells of the finite elements can be triangles or quadrilaterals. The elements are iso-parametric.
