The Orszag Tang vortex system describes a doubly periodic fluid configuration leading to two-dimensional supersonic MHD turbulence. Although an analytical solution is not known, its simple and reproducible set of initial conditions has made it a widespread benchmark for inter-scheme comparison.
The computational domain is the periodic box where
D
is the number of spatial dimensions. In 2D, the initial condition is given by
This test problem does not have any input parameter.
A snapshot of the solution on a 512x512
grid is shown below.
