Hi, i am getting this warning when running a simulation for eiggenfrequency and static step. It seems the software disregards all virtual bolts when running simulation. In structural model creation, the components seem to be disconnected when using ' show disconnected bodies' even though virtual bolts and ties are applied. Virtual bolts seem to work good with smaller assemblies, but problems with larger ones.. The warning is not present for kinematic bolts, but wont run the simulation.

***WARNING: A DISTRIBUTED COUPLING DEFINITION WITH COUPLING=STRUCTURAL WILL
IGNORE THE STRUCTURAL COUPLING AS AT LEAST SOME OF THE NODES IN
THE CLOUD DO NOT HAVE ALL THREE ROTATIONAL DEGREES OF FREEDOM
ACTIVE

***WARNING: A 3D DISTRIBUTED COUPLING DEFINITION WITH ROTATIONAL
COUPLING=STRUCTURAL WILL IGNORE THE STRUCTURAL ROTATIONAL COUPLING
AS ALL OF NODES IN THE CLOUD ARE FROM ELEMENTS WHICH DO NOT HAVE
ALL ROTATIONAL DEGREES OF FREEDOM ACTIVE
