Hi all,


I think my bridge model is now constrained fine, but somehow it is not able to converge.

I think it is due to the large penetration within the contact between line bodies (beams). For example, in the bottom graph, I tried to create a contact between the green highlighted beam with those three red highlighted beams. I designed these line bodies in DesignModuler and ensured the vertical and horizontal lines touched each other without any penetration. But the initial contact result keeps on telling me that there are penetrations (orange) no matter how I change the pinball radius. May I ask if this is due to the rectangular cross-section I am using now?

Thank you.
