Hello, I am looking for software that I can use to computationally determining the flowfield over a 3D swept wing. Perhaps using a vortex lattice method. I have very little experience with any kind of aerodynamic computational modeling. Is what I really need to do is be able to put my wing geometry in the program to determine the baseline flowfield characteristics such as the velocity distribution including the spanwise velocity component. Then I will need to remove a section of the wing and and determine how the flow field has changed. For example I would remove perhaps from midspan to the tip and determine the flowfield over the portion of the wing that remains. If possible I would also need to model wind tunnel walls and the effects they have on my model. Does anyone know of any programs that are capable of this. Like I said I have very little experience with this sort of thing. Thanks for your help.
