Modeling A
==============


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

:math:`\theta` of the schema in time imposed on :math:`1` to test the calculation of the second member in transition.


Characteristics of the mesh
----------------------------

Set to 250 HEXA8 (5 elements on edges :math:`\mathrm{HD}` and :math:`\mathrm{DM}`, 10 elements on :math:`\mathrm{DF}` by IDEAS.


Tested values
---------------


.. csv-table::

    "**Identification**", "**Reference**"
    "T (A) * N1", "100"
    "T (B) N133", "50"
    ":math:`\phi (A)\mathrm{.}Y` ", "15.9155"


*: imposed temperature


notes
---------

The symmetry of the mesh means that solution :math:`T` at the nodes of the mesh is accurate, but in the elements, the extrapolated solution is not exact.

The flow is calculated by*Aster* at the points where the elements are integrated and then transferred to the nodes by extrapolation. As the flow is not uniform, this extrapolation leads to a difference between calculation and reference.
