Need some help and advice in Static Aeroelasticity with Femap/Nastran

Need some help and advice in Static Aeroelasticity with Femap/Nastran

Need some help and advice in Static Aeroelasticity with Femap/Nastran

My name is Vincent, I have to study Static Aeroelasticity on a bridge deck and to do so I began to use Femap with NX Nastran.

After learning the basics and saw a video (https://www.youtube.com/watch?v=O8ZGbmLKv8I&t=...) and follow step by step the analysis but I had no results, the analysis never finished (I let it 10 hours and still not finished).

A picture of the main settings I did attached, I think my problem is from one of theses things :

-Contraints (I just fixed both of the side surfaces)
-Meshing (I did : meshing control --> size along curve then geometry --> solids)
-Structural Grid group to define the spline
-Also I didn't find any parameter in the analysis to control the wind speed

I will apreciate so much any help, even to tell me who could help me or show me an exemple on Femap/Nastran.

Best Regard
