hi . im working on cyclone . i have some problems in meshing it . i cant mesh inlet part of the cyclone either its not compatible or highly skewed . what must i do ? can i remove the inlet section and instead make part of the cyclone body as inlet (i mean something like a hole on the body) ?? does it effect the solution ?
2 . i have used some extra faces in order to mesh it radially ? will it make any problem ? do i have to use connect face for this ??(considering continuum )
here is a picture of the mesh :
thanks for your time .

-mAx- will become famous soon enough
in your picture, you are displaying cells with skewness between 0 and 1... But this value cannot be greater than 1 or negative.
That's why you have 100% of cells between both values
So update your lower value with 0.9 instead of 0 (you will see all cells with skewness between 0.9 and 1)
