Dear Engineers,

In most supersonic flows, shock waves occur as the fluid goes past the object. There are two types of phenomena, an oblique shock (when the flow hits a convex corner) and an expansion wave (when the flow goes through a concave corner). This has a resulting effect on the velocity, pressure, and temperature of the fluid and can lead to increased drag if the aircraft is not designed (i.e. streamlined) properly.

Here is a detailed tutorial explaining how to perform a compressible flow CFD (computational fluid dynamic) simulation on a rocket fin, generating oblique shocks and expansion waves. To facilitate this, you will need to use the 'Face Split' feature in the Geometry section to break up your domain into a number of sections.
