**u3.13.09** 2D_ DIS_T and 2D_ DIS_TR models_
================================================

**Summary:**

This document describes for 2D_ DIS_T, 2D_ DIS_TR models (cf. [:ref:`R5.03.17 <R5.03.17>`]):


* the degrees of freedom carried by the finite elements that support modeling,


* the related support meshes,


* the loads supported,


* non-linear possibilities,


* test cases implementing the models.

2D_ DIS_T modeling allows the representation of discrete translation elements with one or two nodes.

2D_ DIS_TR modeling allows the representation of discrete elements of translation and rotation with one or two nodes.

They can be used for two-dimensional problems in linear or nonlinear mechanical analysis.
