Mesh elements conflict geometry's surface
 

Hi to everybody,

I am trying to make an structured mesh around a wind turbine blade(in the fluid domain). But the problem is that the mesh elements near the blade's surface cross it and comes in the solid domain and this is undesirable. I have attached 2 images of my problem. I would be thankful if anybody can help me on this.

Regards.

Have you checked if all the associations of the blocking to the geometry are correct?

I have checked it twice but I'll check it again,
thanks for the reply

Check for the association of faces to surfaces. I've had similar a problem to yours and found out that the association was taken in a wrong way by the default setting of ICEM.

Like cesarcg said it looks like an associaton error. It could help to add a few splits in z-direction especially in area of high curvature and associate edges to geometry there. Hexa might not work properly if your blocking does not represent the geometry good enough in these areas, even when associations are displayed correctly. Also run check blocks and fix inverted.
