This was 6.2. something. I downgraded to 6.1. One more Question.
When we sizing spar, let's say it is I-beam shape, and spar web is 2-d shell element, and spar cap is 1-d beam element. In concept, should I use Cap beam or Web-beam?
What is difference between Cap-beam and Web-beam? Normal direction? Then how would I set normal direction in rod-elements? Thanks
