Thanks for the suggestions. The robots aren't moving along the structure but their base is fixed in place and they apply forces and moments to the structure at a single point.
We're analyzing a structure with robotic loads on it that can occur at different instances in time. We potentially want to evaluate 65,000 LC's in a solve. Does Risa allow this?
I see in the literature that up to 1000 BLC's are allowed but I haven't found anything on LC's.
