Benchmark solution
=====================


Calculation method used for the reference solution
--------------------------------------------------------

Comparison of results with the CETIM CASTOR -SD finite element software.

The CASTOR element used is an 8-node isoparametric shell element, based on Ahmad's formulation. It is a degenerate three-dimensional element, whose field of application is that of thick shells.


Benchmark results
----------------------


* Displacement and constraints at points :math:`E,F,G` for each harmonic.


* Movement and constraints at points :math:`E,F,G` for total loading.


Uncertainty about the solution
