Streamlines from surface for Navier-Stokes simulations
 

Hi all,

I have done 3D-Navier-Stokes simulations on a model aircraft. We all know, velocity on surface is zero in Navier-Stokes simulations. I want to draw streamlines from surface ( which can be directly done incase of Euler simulations because velocity is non-zero on surface). What is the technique to draw streamlines from surface using Navier-Stokes simulation results? :confused:
