I have a weldment that is to be bolted to another. Therefore,
I applied loads through the tapped holes (16 holes, no threads).
When I apply a force, choose the tapped hole surfaces(parallel
cylinders), and set the magnitude, I get a result that is 10-15x
higher than if I apply the load through the mating surface.
For clarity, the part is basically a hollow cylinder with a circular bolt pattern on one end, with the bolt holes running parallel to the cylinder axis 1.5in deep from the mating face. The mating face is a flat plane.
Why would I have such a big difference in test results? Does CosmosWorks apply the full load magnitude to each bolt hole when I choose multiple surfaces? Or does it evenly distrbute the force among the 16 holes?
As a reference, I built this part and tested it in real life. Loading the mating face in CosmosWorks gave results much closer to the real test.
Thanks in advance.

Thanks to the tech support guru Seth at 3DVision for solving that one.
