Hi All.

I'm currently undergoing my Honors Project as part of my Degree, this project involves the optimization of a power kite.

While trying to determine the lift using ANSYS FLUENT, I'm getting a negative lift coefficient (-0.12 roughly.) Part of the issue for the invalid results is due to my mesh having a Skewness of >0.98.

Having tried everything to try and overcome this issue - by simple refinement of the mesh to resizing the boundaries, no significant change has occurred. Thus I am asking if anybody is aware of ways to rectify the skewness of the mesh? Any help would be greatly appreciated.

Thanks
