Interfaces Problem
 

Hi. I'm currently studying the flapping wing concept, and for that I am using the dynamic mesh feature. To better improve mesh quality, I am using a zone that doesn't not deform and the other part that deforms and between them there is an interface. The problem is that on the interface, sometimes the results are not that pleasant to see (Check the attachment). How can I find a solution for this problem? I have edge sizing on both edges of the domains so they match up.

EDIT:

I think I discovered the problem. In the interface zone, the mesh has not the desired size (see attachment naca0012.png). Is there any solution to this situation?
