Mechanism Dyn. with multi_skeleton models

I am always use multi_skeleton in Mechanism design. It proving successful in kinematics but when I tried to make a dynamic analysis I mean kinetics ( Forces included in the analysis), Always I receive a message "some body in your assembly has a zero mass"???. OK, the skeletons have a zero mass but what is the solution???





kind regards,

I'd also be interested if anyone has got any ideas about this one?



Sam

Try to set a very small desity for the parts, use mass proprties icon in pro/mechanism


This is may not be the best way to do it but is the one i know

In WF 3.0 this has been made possible. Create assembly with all parts using skeletons. Give the skeletons mass_prop using mechanism icon.
