D modeling
==============


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

Discretization of the two beams by two SEG2 cells (1 each) and 2D_ DIS_T finite elements.

The resolution is done using schema HHT without overshooting (``SCHEMA =' NOHHT '``) of the DYNA_NON_LINE operator.


Characteristics of the mesh
----------------------------

Number of knots: 3

Number of meshes and types: 2 SEG2


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

The infinite norm of the difference between the analytical solution and the solution calculated at the level of mass no. 3 is evaluated. This comparison is made for displacement, speed, and acceleration.
