ANSYS Mechanical APDL - LINK180 and BEAM188 - How to use together

[SukiLeinen]

I want to model beam with simple load on center of beam. I am using BEAM 188 element.

The beam is suspended on two cables(tension only).

For my cables, I am using LINK 180 element.

How to connect LINK 180 elements and BEAM 188 element in Mechanical APDL so I don't get:

A large pivot value error.

What is the procedure, is there some tutorial.

Any answer ?

The pivot error message likely means your model is not constrained well in either rotation or translation degrees of freedom. The message following the output error may provide you a hint on where to look. For example: "e.g., at the ROTX degree of freedom of node 4". I'm betting your BEAM188 elements are doing some unexpected somersaults.


Good luck,

It's a Link 180 element that is going nuts

What if I put number of divisions on LINK 180 elements that are my cables to 1 ?
