Contacts - Rigid body to Flexible Body Contacts

[glync]

Hi,

(In Workbench)

To simplify a large static structural and transient analysis I'd like to model some large objects as rigid, but keep the bolts and fish plates connecting them together as flexible. However, ANSYS flags any non-linear contact (frictional) between a rigid and flexible body with a question mark.

ANSYS claims you can switch easily between rigid body and flexible body analyses, but I'm not sure why my contacts are being flagged.

Please help?

Thanks,

Glyn
