Hi everyone,
i have built a mesh on icem 14, when i exoprt the mesh in fluent and i try to do the check, it fails. The problem is that there are some faces with too small area, and there are elements with the minimum Orthogonal Quality below 0.01.

Hi,
thank you for the answer. I've already made the o grid, but the problem is that the mesh finishes in one point (i attach here two picture), and i think that's the real problem.

Yes, it's a 2D geometry used to model a vessel partially filled of liquid. I attach the block strategy.

I think that you should also snap the vertices of the exterior block to the curves. Let me know if you have in mind something else to try. Regards

Hi,
i solve the problem with the vertex moving of the external block to the circle. Thanks.

What you should do is associate your outer blocking edges to the circle and then snap them to it. Next, use the spline tool to curve the block edges; that'll fit the mesh to the outer circle better. Next move the vertexes of your inner (o-grid) block to some arbitrary points well within your circle. that'll get rid of those skewed elements at the corners. __________________ www.idacireland.com
