Well this is a huge problem that is compromosing my work.. It seems stupid but ill explain and i would really appreciate a good answer..

The model description is:
1. I have a model of a bridge with beam44 element.
2. The beam44 elements are defined with beam sections (not real constant)
3. I have some stay cables on the bridge that i want to define with link8 elements

And the problem is:
If I have all my model with beam44 elements, i can mesh the structure and solve it. As soon as I add the link8 elements and define its real constants i cant mesh anything. I try to mesh but the elements dont appear and i cant solve the structure because there are no elements there.

The problem seems related with real constants. Because beam44 elements have a beam section and the link8 has real constants. It seems that the beam44 elements adopt the realconstant set information for mistake, i dunno. I tried to just add the link8 and the real constant without remeshing anything and the problem keeps.

Please help me getting a solution for this problem.
Thank you very much

Hello,

try to define the real constant for link8 as number 2.
