Negative quality elements in ICEM Grid
 
Hi

I use ICEM CFD to mesh a cascade. i get negative quality in quality check only on the suction side of airfoil. And at a particular point, the grid is clustered though i have not clustered the grid. Also at some spots meshes overlap.

Kindly suggest me some remidy and the probable reason

Thanks Kartik

I would check edge projections/associations first. You can also view the edges with the projected shape (Edges options Nodes)

What mesh are you using? Try hexa. If you're using tetra, then try CFX-Mesh.
