First your warmly welcome to sw forum.
My comments for your question
1.first you can create simple model & add condition (you can guide attached pic) try to simulate. if simulate finely it recognize simulation program has no doubt.
2.check your tutor1.SLDPRT simulation condition correctly applied.(guide same attached pic)
If both steps are ok, i hope you have to do better.
