Thank you for your response. However, the assumptions you made about my knowledge in case of CFD is fascinating. I am seeking a suggestion to approximate that load which I will get from FSI simulation on this part, but there are some constraints due to which I do not wish to perform FSI and then transfer those loads to structural analysis. 

With all due respect, your response is asking me to ignore the loads due to the airflow over that part, but I am seeking exactly how to approximate such forces with purely structural analysis with this problem. Thank you for your valuable suggestions to tackle this problem and I really appreciate the help.
