@peteroznewmannThank you Sir! I really appreciate all the effort you have put into this answer and it is a life saver. I especially found helpful the way you pointed out for specifying the mass of the aircraft. I have a question if you can answer as well I will be very grateful. If I have to simulate the problem in ANSYS ls dyna or explicit dynamics, do the conditions as specified in your answer change? Can you also give me guidance on that front as well? Again I am very grateful for your help. n
