Hi. I'm unable to add bolts between the two beams. I had SolidWorks do it automatically before, by converting all fasteners to bolt connections, but I was unable to run the simulations, then I tried adding bolts manually, and it tells me "cannot define bolts on beam". I tried adding contacts between the beams, but still, I'm unable to add the contacts. It says "invalid entity on beam body was selected". Please, I need a workaround for this.
