3-D WIG above free surface
 

Dear friends,

I am trying to simulate the flow around a WIG craft above free surface. The deformation and Cp distribution are not good. Mesh structure is quite good, mesh refinements are already employed around the wing and free surface. I am looking forwaard for your valuable advices on this topic.

3-D NACA0012
AR=8
AoA=5 degree
c=1 m
Ground clearance (h/c)=1
0.3<Fn<1.5
