Hello,
Computational Fluid Dynamics (CFD) is one of the Finite Element Analysis (FEA). CFD is performed to get the simulation of airflow around an air craft. At times the wind speed will be very high and the wind speed fluctuates and the velocity, pressure on the contour changes so it is important to do this CFD simulations on an aircraft to study the effect of airflow. And finite element analysis helps in achieving this required simulations by discretizing each element, applying loads, calculating the unkown parameter with predefined parameters.
