Hey together,

I need to evaluate bolts in detail. And i am extracting the reaction forces out of my model to do an VDI2230 assessment, based on the FE results.

I need to create the force and moment reactions for every bolt by hand. Now I asking myself if there is a faster method to do it automaticaly or to extract the reaction loads for all bolts. The object generation does not work for that.

Have you tried the Bolt Tools Add On for Mechanical (2022.2 and above).  This has a feature to automate force and moment reaction probes with a CS per the local orientation of the bolt.  This can either be done by creating a construction surface that splits the bolt shank, or you can post process on the bolt seating faces the reaction loads.
Once you have automatically created the objects in the tree (can be for single time point, all, or user selection) these values are auto-generated into a .csv report that can further be used to do post processing in Excel for example.
After you have done post in Excel, you can finally use the tool to cross-reference between the final results and the objects in the Mechanical tree.  

To access this functionality go to Add Ons on the ribbon and active Bolt Tools.
In the new Bolt Tools tab in the ribbon go to: Wizards>Reaction Probes Wizard
This will bring up a side panel to interact with and start the automation process per the above description.

wow thats really great. I missed that tool during the last update! 

It is creating the full reaction force for all the bolts in the csv file. I need to adapt the interface of my bolt evaluation, but at the end this is what i searched for! 

Thanks a lot!
