Hello,
Creo3.0 M030
Just checking, Can someone confirm a positive separation stress means surfaces are trying to separate?
I get the following in the log from both the studies below:
' The fix separation option for the fastener is preventing the parts from
separating at locations where they should separate. Hence, the results
for this analysis may be inaccurate. You should turn off the fix separation
option for the fastener and, if desired, introduce a contact interface
between the parts that are connected by the fastener.'
Thanks
