[ICEM] problem with meshing 2d airfoil

puppypuppygo · October 29, 2016, 05:00

When I mesh a domain of 2D airfoil, some errors occurs.
I set the unit to "meter", and the chord length of the airfoil is 1m. Then I set the maximum size of the wall of airfoil to 0.0001m. But the airfoil was ignored.
When I set the maximum size of the wall of airfoil to 0.001m, it was meshed correctly.
Why did this happened? I couldn't find the reason now.
Thanks for anyone who can help me with this problem, thank you

If i were you I would do blocked structured mesh rather than this approach

As Shereez said you'll be way more efficient using a blocking strategy. This is well documented, you can even find a nice tutorial that Simon made some time ago : https://www.youtube.com/watch?v=tYrbScUH9RE
