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.

You have to go to edit mesh option , apply flood field , here you can save the mesh in the region you want.

thanks pratik mehta. but what i have got in "edit mesh :flood field is concerning tetra mesh only.and i dont get it for the hexa mesh. but i have done it easly with an other manner.whith deleting block.

use create part option from parts.Name the part and add the airfoil block to it.While doing pre-mesh switch off airfoil part.This will solve the problem.Just check.
