Tutorial OS-T 3200 Design of a Composite Aircraft Underbelly Fairing - What is MAXSUCC, MSUCC, VSUSS

Hello,

I am doing this tutorial OS-T 3200 Design of a Composite Aircraft Underbelly Fairing. I am doing the last phase, phase 3, and in your instructions you MSUCC. Where can I read more about this in the help? This number is the maximum successive number of plies of a particular orientation? Correct. What about VSUCC? Thank you very much.

I run it and get a message "INFEASIBLE DESIGN (AT LEAST ONE CONSTRAINT VIOLATED)." What should I look to change to correct this? In the tutorial this analysis converged.

Also, I received a message: " NOTE # 1852
AUTOMATIC SCREENING is activated.
Use DSCREEN,AUTO,OFF to disable automatic screening."

Where can I find and change this? Thank you.

At the end of Phase it is written "After the free-size and size optimizations, a weight reduction of ~65% of the original design was achieved without violating any of the prescribed design constraints" Where can see the weight reduction? Thank you.

Hello, after doing the phase 3, I got a message that the design is not feasable because freq1 is above 0.02. The value is 0.0197. By changing this to 0.019 the analysis converges, and the solution is found after 2 iterations. Can you comment on this? The other results I got in phases 1 and 2. Thank you.

Hello, also in the new interface how can me create the new window so the results are next to the original fem model? Thank you.
