RinglebMeshGenerator
Creates a mesh for the Ringleb problem.
Overview
This mesh can be applied to a Ringleb problem. This problem tests the spatial accuracy of high-order methods. The flow is transonic and smooth. The geometry is also smooth, and high-order curved boundary representation appears to be critical.
Governing Equations
The governing equations are the 2D Euler equations with .
Geometry
Let be a streamline parameter, i.e., on each streamline. The two stream lines for the two wall boundaries are for the inner wall, and for the outer wall. Let be the velocity magnitude. For each fixed , , the variable varies between and . For each , define the speed of sound , density , pressure , and a quantity denoted by by:
For each pair , set:
Mesh Example
For example, let's consider the following input file:
