Post your assembly using Pack and Go so it's a .zip file. Opening a .rar file is a pain for a lot of people. The only app' I have for it is on my old Mac. Not that I could help you with your analysis anyway, but make it easy for others who might.
Also, not that there aren't some pretty sharp people over in Yakima, but you might reach a wider audience if you move your post to the Simulation, or maybe the Modeling and Assemblies space. I'm not sure how you do that, but I'll bet something in here How do I do this SOLIDWORKS Forum thing? will point you in the right direction.
