beam beam contact explicit 1

[cedarwinter]

Good Afternoon,

Recently I used ABAQUS/Explicit to model beam to beam contact. There were two parallel circular beams (the gap between two is 2.1 and radius of each is 1) of B32 elements. A general contact was assigned to all automatically recognized surfaces as below.
*Contact, op=NEW
*Contact Inclusions, ALL EXTERIOR
*CONTACT PROPERTY ASSIGNMENT
,, contProp1
However, beams weren't recognized in contact and one beam penetrated into the other as a result. I read that Explicit general contact automatically include surfaces in contact domain and beams of 3d beam elements are activated by their inclusion in the contact domain. Also, there should be a radius for the contact edge of a beam. Is there any proper way to detect B32 beams in general contact (edge to edge contact) in Explicit? I read previous threads but didn't get a clear answer.

Many Thanks!

Check warnings in .sta file. Maybe your mesh is too fine, so the contact thickness needs to be reduced to prevent self contact.
