Using Inventor 2014 and I am trying to run a Simulation for a Stress Analysis and before I hit run, I have a Warning that says that there are no contacts attached to 4 different bodies of my assembly.  It will let me run the simulation with the warnings, but have no idea why this is showing up even though I have a number of different bonds associated with each body.  Any Ideas? Thanks

share your model lets see which parts are not in contact

I am new to Inventor, not sure what all you need to do this?  What do I need to do?

what will happen if you hit 'run'?, will it proceed with the test analysis?

yes, it runs the analysis and shows deflection and stress, just didn't know if there was an issue with my model.  Will I be safe to leave it as is then?

I also did try 'test analysis' and had some pre warnings but proceeded and I leave the computer for 2 days running and finally have the results. I think you should try to do the same
