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


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

The mesh is done using TRIA6 of the D_ PLAN_HM_P modeling.

The aim is to test the solution in terms of movement and pressure given by *Code_Aster*. We also test the computer non-regression of the calculation of the residual error indicator for permanent HM modeling.


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

Number of knots: 43

Number of meshes and types: 16 meshes TRIA6

The mesh is refined uniformly 1 times using HOMARD.


Tested sizes and results

* Before remeshing


.. csv-table::

    "**Point**", "**Component**", "**Reference**", "**Code_Aster**", ":math:`\text{\%}` **difference**"
    ":math:`P` ", "DX", "2.941E-04", "2.941E-04", "6E-03"
    ":math:`P` ", "DY", "0. ", "4E-18", "0.000"
    ":math:`P` "," PRE1 ", "131250. ", "131249", "-2E-03"


We also test the computer non-regression of the global components ESTERG1 and ESTERG2 of the error indicator. Absolute tolerance is therefore severe: :math:`{10}^{-13}`.
