Hi
I am working on wing geometry with sinusoidal leading edge, the wing is in a cuboid, which has to be meshed.
I hav applied the Boundary layer for wing faces and clicked on view BL option......it shows up that "mesh of volume contains 234 higly skewed and 185 inverted elements"

I jst ignored it and proceed to mesh volume with tetrahedral, T-grid option, it shows up that "ERROR: TG mesh domain failed with error code1
ERROR: Tetrahedral meshing has failed for volume.
This usually caused by problems in the face meshes.
check the skewness of your face meshes and make sure the
face mesh sizes are not too large in areas of small gaps."

to reduce skewness i have reduced the sharpness of trailing edge, but it doesnt worked. please help me to mesh the geometry.

Thanks a lot and sorry for the large text.

check your geometry, you may have small edges or small faces, without appropriate mesh on it.
When you mesh the volume, it is possible that gambit warns you about face mesh that failed (with face id).
Just check the topology on those face id, and correct it (if you can)

Thank you for your time.
yes it does hav a small face with 0.003in*5, its a trailing edge face.

but if i adjust the size function to obtain good face mesh, it results in coarse mesh in volume by which i might be unable to capture flow properties in BL.

and ofcourse i do hav a prob with huge number of cell volumes, because Fluent coudnt handle too many due to memory(m_alloc error), so im trying to get an apt volume mesh.

Don't you have the possbility to merge those small faces?
Else you can split your volume, the aim should be to isolate this area, and mesh it with appropriate cell's size
