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


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

Modeling: **DKT**


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

Knots: 16

Meshes: 9 QUAD4


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

Three calculations are performed with the DYNA_NON_LINE operator, the first with an explicit schema, the second with a weakly damped implicit schema (HHT) and the third with a heavily damped implicit schema (HHT).

All tested values are taken at time :math:`{t}_{\mathrm{max}}=0.0012s`.

**Calculation 1: explicit**
