[ICEM] Problems meshing an airfoil with ICEM

Bert9 · June 19, 2014, 07:34

Hi,

I´m trying to do an hexa mesh with ICEM for a compressor blade. In order to do that, I splitted blocks and I used an O-grid block in the center.

As I got the premesh, there were problems with the it in some blocks. I don´t understand them because everytime I try to do it the problem comes in a different block. The block that was wrong last time is now right and so on.
Eventually I managed to do it right (image attached "correct"), but now when I change something (smooth, refinement, move vertex) this problem appears again (images "error 1 and 2").

Does anyone of you know what might cause this problem and how to solve it? I don´t know if it´s a geometry problem or a problem doing the blocking with ICEM.

Thank you for your attention.

r u able to solve problem?

Nope. I just tried several times building all up until I finally got the right mesh. Still I can't tell why it went right that time.
Any suggestions where this problem comes from?

common error is due to wrong association.
