how to draw surface streamline in CFD-post?
 

I want to draw surface streamline on the 3d-wing surface, but when i use the surface streamline in CFD-POST, it didn't work, i can't see any streamline. i know the velocity on the 3d-wing surface is zero, but the User's Guide shows the program can do this job. ps:i know how to use CFD-post to generate 3d streameline.

who can help me :confused:

I suspect CFD-Post uses wall shear to generate the surface streamlines. Have you included wall shear in your output file?

thank you for your advice，I have alreday draw the surface streamline.Just like you said that CFD-Post uses wall shear to generate the surface streamlines and the wall shear information should be given. when generate surface streamlines in the software, the wall shear in the variable list should be chosen rather than velocity then surface streamline is visible.
