I am in a beam study with two tapered beams, two curved beams a a slew of regular beams. When I set one end of the tapered beam to hinged and try to solve I get "Beam element as zero cross-sectional area at element:89 Check real constant set:15". If I turn the connection back to rigid it goes away. The study is very simple, without and special connection types or unusual loads. Anybody have any thoughts?
