Recently i have found out that the bolt preload can be modeled using advanced fasteners in ProMechanica.
Unfortunately when i set the fastener to include this modeling capability, i receivethe followingwarning in the report of the analysis:
"The local point measure fastener*_separation_stress has no elements associated with it. A zero value will be assigned"
It happens for each fastener (number *) i include in the analysis. I tried tofix the problem varying the separation test diameter but it doesn't work. I also checkedthe effects ofchanging all of the other bolt parameters without success
.
This problem leads to compute a 0 separation stress. May thismistake affect the contact analysis, when contact regions are included?
May someone help me to fix the problem? Thank u very much in advance
