Hi guys,
I implemented an adaptive mesh refinement based on Courant number on my problem. I'm studying a sonic jet and the algorythm works in this way:
I chose a time-step for the entire simulation and the mesh is generated point by point so that the final Courant number is about 1.
I make the time step independence study changing the time-step, and decreasing the time-step I increase the number of cells too.
If I reach a time-step convergence, can I say that that case is also grid independent?
Thanks in advance,
Gianluca
