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.

DesignModeler – Thin/Surface

The Thin/Surface feature allows you to convert solids into thin solids or surfaces. The feature can operate on both active and frozen bodies. Typically, you will select the faces to remove, and then specify a face offset that is greater than or equal to zero (>=0). You can make a model’s thickness in one of three directions of offset:

Design Modeler – Connect

The Connect feature can be used after the Share Topology feature to selectively share faces between two bodies of a multibody part. You will need to specify a tolerance and ANSYS DesignModeler will connect two faces into one face if the faces lie within the specified tolerance.

Design Modeler – Mid-Surface

The Mid-Surface feature allows the creation of Surface bodies that are midway between existing Solid body faces. The resulting surface body/bodies have a Thickness property which defines the “thickness” that surface body represents. The faces can be…

Design Modeler – Symmetry

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.
