Reply To: Beam-to-Beam Contacts

[Alex R.]

Hello Thomas, 

In a single surface contact (A_GENERAL and A_SINGLE_SURFACE) the elements should be on a surfa (slave) side of a contact. Master side (Surfb) is not applicable for single surface contact. 

In your case slave (surfa) is null. To make this contact work change SURFA with SURFB, assuming that Set PID = 2 exists. 

Please find out the article about beam-to-beam (shell_edge) contact: /knowledge/forums/topic/how-to-model-contact-between-beam-elements/

Thank you,
Alex
