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


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

3D_ THH2MS modeling on 1 HEXA20 mesh.

1 second is simulated by 10 steps of time.


Result of modeling A
-----------------------------

The :ref:`Figure 2.2-1 <Ref200252076>` shows the evolution of the displacement dY as a function of time (the evolution is the same in the 3 directions, the test being perfectly symmetric). The post-processing is here done at node :math:`\mathrm{N8}` at coordinates :math:`(\mathrm{0,5 };\mathrm{0,5 };\mathrm{0,5})`. We make sure that travel evolves in a positive way.

A strong acceleration of the swelling is constant starting from 0.7 s, which corresponds to the moment when the swelling pressure stabilizes at 7 MPa (see above).

Tested sizes and results
------------------------------

This test case has no reference value, so we make it a case of non-regression.

A test is carried out on the 3 directions:
