WIND-US time stepping
 
Does any one know what is the default time stepping method in WIND-US? I know the default explicit operator is Roe's second order upwind biased flux diff splitting. Thanks

The following info on obtaining the Wind-US code is taken from: http://www.grc.nasa.gov/WWW/winddocs...obtaining.html

Wind-US, and the associated pre- and post-processing tools, are releasable (for free) to all U. S. owned companies, public and private universities, and government agencies. However, only U. S. citizens and resident aliens may have access to the software. In general, requests from foreign owned, controlled, or influenced (i.e., those with nonresident foreign nationals on the board of directors) corporations will not be granted. Instructions for becoming a registered user may be accessed from the NPARC Alliance home page: http://web.arnold.af.mil/nparc/ or more specifically from: http://web.arnold.af.mil/nparc/NPARC...tructions.html

The timestepping in Wind-US is described at: http://www.grc.nasa.gov/WWW/winddocs...rical:timestep

The default is first order Euler differencing. Other options include second order, global Newton iteration, and multi-stage Runge-Kutta.
