[ContactStructuralMechanics] Missbehaviour of the normal definition

[AlejandroCornejo]

Hi!

Recently I've been generating cases with GiD for the ContactStructuralMechApp and, despite I've checked that the normals are ok in the preprocess, in the postprocess the normals are backwards....

I'm wondering if something has changed in the normal condition generation :)

PD: Currently the ptype is writing ""raileigh_alpha" instead of "rayleigh_alpha" which throws an error.

Thank you kindly,

Alejandro

Hi @AlejandroCornejo Could you attach an example of that backward normal issue?

I'm checking the rayleigh_alphaone

here you have an example :)

Hi Dr. @AlejandroCornejo , I've tested your case (changing a bit the end_time and the pressure and I got this contact

I don't know about that normal direction issue, but I think this is not the expected contact

Hi @jginternational ! This example has already 2 years so maybe I have to check everything (who knows). What do you prefer? I try to generate a new one or updating this one?

I was planning to create 2 examples (2D and 3D) for the Structural mechanics application where we can see the contact working. Maybe it's a good moment to close this issue and create those examples from an existing and working test
