Good Evening,

I am having some issues with dynamic stability... I have a horizontal run that goes through a wall penetration then turns upwards through a LR elbow.

After my wall penetration I have a structural angle that is going to provide lateral restraint and hold the weight of the vertical pipe.

Once the pipe goes vertical I have two more structural angles that protrude from the building exterior and using a U bolt will restrain lateral movements.

So, when the first vertical support is 2'-8" away from the centerline of the horizontal support everything works out. When I lower that vertical support by 1', I get the rigid body error. Is there any way I can add a some artificial friction or snubbing to nudge the solver forward.

Unfortunately I have to move this support down...

Thank you in advance.
