ANSYS FLUENT

ANSYS FLUENT – NACA 4412 – Airfoil 3D

The amount of lift generated by an object depends on how much the flow is turned, which depends on the shape of the object. In general, the lift is a very complex function of the shape. Aerodynamicists model the shape effect by a lift coefficient which is normally determined through wind tunnel testing. For some simple shapes, we can develop mathematical equations to determine the lift coefficient.

ANSYS MESHING – Pinch

The Pinch feature lets you remove small features (such as short edges and narrow regions) at the mesh level in order to generate better quality elements around those features. The Pinch feature provides an alternative to Virtual Topology,

ANSYS Meshing – Element Order

The global Element Order option allows you to control whether meshes are to be created with midside nodes (quadratic elements) or without midside nodes (linear elements). Reducing the number of midside nodes reduces the number of degrees of freedom. Choices for the global Element Order option include Program Controlled, Linear, and Quadratic.
