Hi everyone,

I am learning ICEM. When I try to create a structural mesh for a 3D NACA0015 airfoil-shaped rocket (1/4 part), I find there is messy surface mesh on boundary surface. I have used Ogrid block and moved vertex to fit boundary surface. Could anyone suggest some advices? Many thanks for help. The screenshots are attached as following.



This is the blocking strategy overview.


This is the whole meshing outlook.


This is the overview of a meshing slice of z cross section.



These two pictures show details about messy boundary surface mesh of the z-cross-section slice.
