I’m creating a parametric cable arch bridge. I have analysed the model in one arrangement of hangers but as soon as I change the number of hangers or hanger angles I get an error saying I have rigid body modes in the system. I have tried using the eigenmodes component but still no luck. Is there any way to find out which members are moving freely and causing the issue?
I have attached my file below
