Meshing Quality

Hello,

 

I'm optimizing the layup of this structure using Optistruct and right now I'm trying to do a mesh convergence study to get the best possible results (tried optimizing with a defined element size but the optimization would not converge).

 

When using 2D Auto Mesh I get a regular mesh pattern on most of the surface but then I get some random results in some random areas. On the menu after the meshing process I've tried adjusting mesh density along some edges but I've yet to come to a good result.

Does anyone have any suggestion to improve the mesh quality?

 

Thank you very much!
