Thick 3D boundary layer on blade in annular volume of fluid

Posted by Abraham Vivas at September 10. 2018

Hello,

 

I'm trying to make a viscous layer on a blade inside a annular volume of fluid, but the hypothesis of viscous layer within the NETGEN 3D algorithm distort and skew the mesh near the ends of the blade.

General view of the boundary layer with problems: https://ibb.co/eiUDH9

Detailed view: https://ibb.co/cJh3jp

 

I'm missing something? there is a way to make it works and build a "thick" viscous layer of good quality on a blade inside an annular domain?

 

Kinds regards,

Abraham.
