I'm working on a project that consists on the modelling of a rigid overhead contact line ( rigid catenary).

I need to simulate the contact between the pantograph of the train and the contact line.

In order to decrease computational times ( more than 1 day) I want to consider the overhead contact line as a beam. According to the properties of the pieces, this is a good simplification.

I'm working on a non lineal dynamic analysis.

The problem appears when I define the no penetration contact between the pantograph (solid body) and the catenary (beam), which is not allowed.

I can select faces of the beam, but then I can´t confirm the operation.

I attach some images in order to clarify my doubt.

Big thanks.
