[ICEM] unstructured wing mesh generation in ICEM CFD

arunintn · February 8, 2013, 05:35

I'm trying to mesh a wing geometry in ICEM cfd but i can not make it clean. It has hole in trailing edge

. the geometry was created in solid works. I tried to decrease the size of the cell. but it was same. any suggestion to get boundary capturing.

I like to know why and how to solve this problem. I have attached the picture for reference.

Thank you

problem solved!!!

the most case if we have sharp edges in our mesh. we need to change the value in edge criterion to capture the geometry's knife edges. if it is not working good the final option is to refine the geometry

it is in mesh > volume mesh parameters > edge criterion.

What value did you set for edge criteria ? Default value is 0.2

i changed value from 0.2 to 0.05

Thank you
