Maximum Aspect Ratio
 
hello,

i have a mesh with max. aspect ratio 47
which is very high, I know. I have a tetra mesh with prisms which i generated that way:
1. ocetree
2. delete volume elements
3. smooth surface elements
4. delaunay
5. smooth (10) / laplace smooth (10 iterations) several times, all elements quality >0.3
6. prism (0.6 init height, 1.1 ratio, 3 layers)
7. smooth until quality is >0.25 with low iterations (4) all elements

General comments?

Aspect Ratio in in ICEM CFD is >0.2
Are my problem elements in FLUENT the (few) elements in ICEM CFD that have quality between 0.2 - 0.3 ?

Can FLUENT show me the worst element?

Thanks!
