8. F modeling#
8.1. Characteristics of modeling#
The modeling consists of 112 COQUE_3D elements for the tubular section, and 2 pipe elements to apply the boundary conditions. The length of the shell mesh is \(\mathrm{0.98m}\). The length of each pipe element is \(\mathrm{0.01m}\).
A COQUE_TUYAU connection is applied to each end of the shell mesh, with a pipe element. In addition, the degrees of freedom of the pipes that correspond to mode 3 of ovalization are blocked: \(\mathrm{U03}\), \(\mathrm{V03}\), \(\mathrm{W03}\)
