hello sir,
i have to simulate flow around a NACA0015 airfoil at diffirent angle of attack using CFX. i have create a 2d extruded mesh using scripts file option(file.txt) on ICEMCFD Hexa (multiblock topology).but this is done considering angle of attack equal to zero. My question is: what have i to do, to introduce different angle of attack? is there any possibility to introduce the angle of attack after having the 2d extruded mesh?or have i to do this at the tetin file (geometry file)?and how? please,i will be greatfull to recieve any idea. |

Hello,
you don't have to do anything in the mesh for putting angle of attck of the flow.But while solving using CFX ,in the boundary conditions for the incoming flow put u and v component of the velocity corresponding to the required angle of attack. i.e u=Vcos(aoa) v=Vsin(aoa); V is the resultant velocity. |
