ANSYS FLUENT – NACA 4412 – Airfoil 3D

July 21, 2019

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

ANSYS MESHING – Multizone + Inflation + Face Meshing

October 31, 2019

The MultiZone mesh method provides automatic decomposition of geometry into mapped (structured/sweepable) regions and free (unstructured) regions. It automatically generates a pure hexahedral mesh where possible and then fills the more difficult to capture regions with unstructured mesh. The MultiZone mesh method and the Sweep mesh method operate similarly; however, MultiZone has capabilities that make it more suitable for a class of problems for which the Sweep method would not work without extensive geometry decomposition.

June 16, 2018

The Symmetry feature is a tool used to define a symmetry model. The feature takes either all the bodies or selected bodies of the model as input and accepts up to three symmetry planes. You can choose either full or partial models to work with. If a full model is used, the selected symmetry planes will slice off the model and only a portion of the model will be retained. The valid body types for this feature are surface and solid.
