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


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


* The pipe is meshed into shells (3D shell elements).


* The ends are meshed into beams (POU_D_T) to be able to easily apply boundary conditions.


* This modeling is a reference solution for A, B and C models, in particular for out-of-plane bending where published results are not available.
