v2.02.102 SDLL102 - Gantry subject to electrodynamic forces

Summary:

This test is a three-dimensional problem of direct transient dynamic calculation with distributed forces of electrodynamic origin applied to a gantry (bar on 3 insulating columns of a transformer station).

This test was provided by the Center for Transport Network Studies (EDF - DEPT). It has since been supplemented by an international benchmark established on the basis of experimental measurements (results of several foreign codes): test CIGRE -structure D.

It makes it possible to compare displacement results with those obtained by other industrial codes using a finite element or finite difference method.

This test contains modeling with elements of type SEG2.
