C modeling

Workflow of the TP
----

It involves implementing a mesh adaptation in a Python loop on an elastic calculation.


Mesh adaptation
----

After launching the AsterStudy module and using the modeling command file A, a python loop is added to make two adaptations (Menu Operations → Text mode). You can take inspiration from the file forma01c.comm.

We start the calculation.

After launching the ParAvis module, the following post-processing is performed:


*   See the effect of adaptation on the maximum of the SIYY component of the constraint field. The maximum is now in the order of :math:`280\mathit{MPa}`.


*   Visualize the error indicator map (component ERREST, total error).


Tested sizes and results

Value of the stress components for the initial mesh and after an adaptation:

    "**Mesh**", "**Location**", "**Identification**", "**Reference (Analytics)**", "**Tolerance**"
    "1", "Node :math:`B` ", "Constraint :math:`\mathrm{SIYY}` ", "303.0"," 5.0%"
    "1", "Node :math:`A` ", "Constraint :math:`\mathit{SIXX}` ", "-100.0"," 15.0%"
    "2", "Node :math:`B` ", "Constraint :math:`\mathrm{SIYY}` ", "303.0"," 2.0%"
    "2", "Node :math:`A` ", "Constraint :math:`\mathit{SIXX}` ", "-100.0"," 3.0%"
    "3", "Node :math:`B` ", "Constraint :math:`\mathrm{SIYY}` ", "303.0"," 1.0%"
    "3", "Node :math:`A` ", "Constraint :math:`\mathit{SIXX}` ", "-100.0"," 2.0%"


These tests on analytical values are supplemented by non-regression tests.
