pin-lug contact with cgap elements

Hello,

 

I am trying to perform contact elements but with cgap elements. But once it solves it seems to be that they do not work properly. I guess it is because orientation. 

steps I did:

- cilindrical coordinate system at the center of the pin

- orientation : radial regards this coordinate system

- gap property: set to this cylindrical coordinate system

 

Nodes are coincident between both parts.

I have used this elements before but always rectangular system and I did not find any problem. That's the reason that I think I am doing something wrong with the orientation

Dear Jon,

Not need at all to assign a cylindrical coordinate system to CGAP elements, set OFF the ORIENTATION CSYS in the CGAP property (default 0..Basic Rectangular), simply orient the CGAP elements using the global axis coincident with axial axis of red body using command MODIFY > UPDATE ELEMENTS > LINE ELEMENT ORIENTATION, and you are done!.

Best regards,

Blas.
