Hi all,

I have a simple question

I attached two pictures.

I want to mesh the cylinder in ICME like the quarter of cylinder meshing that i made in ansys meshing (sweep method).

i mean i do not have the center block in the center of cylinder, just like the quarter part, just radial meshing.

is it possible????/

For this, I used quarter o-grid instead of Y-block. But mesh/blocking will be same with both methods.

so you mean that it is not possible to mesh without the center cubic part.
i want to be all radial mesh.
