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.
Please, help me

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.

Is the geometry 2D? can you post some pictures of your blocking strategy?

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

Hi zacfranki,

Did you draw the line at the top of the circle to represent the level of the liquid filling the vessel? 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.

Your mesh is still pretty poor quality. 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.
