C modeling
==============


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

Modeling COQUE_3D, TUYAU, and POU_D_T

One cylinder half (:math:`0<X<L\mathrm{/}2`) is meshed into shell elements, the other half is meshed into TUYAU elements.


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

Number of knots: 436

Number of meshes and types: 100 QUAD9 (modeling COQUE_3D), 5 SEG3 (modeling TUYAU), 4 SEG2 (modeling POU_D_T)
