Dear all,
I am learning to use pointwise meshing. However, when I followed every step in tutorial and tried to mesh the airfoil it was wrong finally. The mesh is like below.
I am just curious about the reason and have you ever encounter this problem?
Thanks a lot.

The inner loop (around the airfoil) is the wrong direction. Inner loops must be in the opposite orientation from the outer loop.

Select the domain
Menu Edit, Add/Remove Edge...
Begin remove inner edges
Select the inner edge
End remove edges
Select inner loop connectors
Flip orientation (if needed)
OK

Hi, David.
Thanks for your reply. However, the button "add/remove edge" is grey, cannot be selected.

You must first select the domain BEFORE going to the menu.

Depending on which version of Pointwise you are running, you can hover your mouse over the grayed out menu item and a tooltip will display with information.
