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????/

thanks in advance,

meysam

yes it's possible. you will then not use an o-grid.when you perform your initial block, merge to vertices to make it like a triangle then transform the block to an y-grid. it's much suitable for this situation. may be there is another blocking strategy , this one is the only i've got in mind now.

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.

Possible. But in that case you will have the prism elements in the center
