Hello Everyone

Can anyone help me in improving the mesh quality. I have attached the blocking, mesh and mesh quality screenshots below. I have  tried using the smooth meshing tool,but it didn't work. My Domain is a C grid of 3m in z direction. The  airfoil width is 1m which is at the center of

grid.

The blocking looks about right, and follows most of the classic tutorial examples. Have a look at the cell size and think why you're getting cells of poor quality in those regions: what's happening to those cells?

There are some 600 bad elements which have a bad angle of less than 18 degrees. How can I improve the angle of elements at the block corners?

You may need to change the angle of the blocks or review the local sizing.
