**v1.01.239** ZZZZ239 - Validating the calculation of the non-symmetric matrix for the elements DKT
===================================================================================================

**Summary:**

This test validates the calculation of non-symmetric matrices for elements DKT
(application with law ENDO_LOCA_TC).

The test consists in applying a loading of shear to a plate.
modelled by elements TRIA (modeling A) or QUAD (modeling B).
The use of a symmetric matrix led to an absence of convergence.
The number of iterations for convergence is comparable to the equivalent 3D case.
