hello, i am beginner in ICEM CFD.i have to simulate a flow over a NACA0015 airfoil.i have the final blocking.but when computing with pre-mesh,all geometry(the external flow+internal surface of airfoil)will be meshed.then i have to avoid the internal airfoil mesh. please,i will be grateful to receive any idea. thanks.

Hi,

you have to delete blocks which are inside airfoil boundary.

Dont delete the blocks but make in vorfn that means the blocks are not consider for meshing

thanks a lot, marek and Ramesh.K. i think it so easy with ANSYS ICEM 11. deleting block,but not permanently,will take block in VORFN. i do it easyly.
