Hello,

I'm new to icem maybe someone can give me a little help.
I try to mesh (hexa) a diagonal cylinder. I used blocking and rotated the block within which the the cylinder is 45 degrees. That block is a OGrid and i associated the edges from the OGrid to the cylinders curves(pictures).
The problem is if i read that mesh in Fluent (after translation in icem etc.) the cylinder is missing.
Maybe someone knows how to handle tis problem or a better way to mesh the cylnider
thx

Meshing done,just attaching blocking file so you can idea about splitting and association.

Sory for quality have "less time" reached min ortho 0.7. rest you must do it yourself

Fantastic. I have improved some angle issues in blocking, but it is less than .00000001 % effort, originally put by nitinbansal184

Really great but how you have done the inclined cut in the vicinity of inclined cylinder(this has made the job simple for you)?

If I am not getting you wrong you mean to say that you have done the blocking of cylinder in vertical position and then tilted the blocking at the angle, is it so?
