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


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


* Modeling in plane deformations.


* 100 :math:`\mathrm{Q4}` elements of equal width for a total length of :math:`20` m.

*Note*: like all THM models, the mesh must be quadratic, but the numerical processing is done on :math:`\mathrm{Q4}`.


Model A result
-----------------------------

Discretization in time: 10 :math:`50000s` time steps each.

Modeling A contains a second calculation that checks the possibility of mixing THM elements with non-THM elements, including in dynamics (DYNA_NON_LINE).

This second calculation (which is in fact purely computational) does non-regression tests on the same quantities and in the same places.
