June 4, 2013, 09:20	Drag	#1
ashishtbm New Member Ashish Kumar Join Date: May 2013 Posts: 4 Rep Power: 13	I am simulating a 2D naca 0012 airfoil under invsid conditions but I am getting positive drag which should e ideally zero for inviscid case and streamline should turn at the trailing edge to up surface. Even cylinder also ideally gives zero drag under inviscid conditions. So, why fluent is giving pressure drag under inviscid conditions?
