rhoCentralFoam / sonicFoam
 
Good day,

i have some questions for rhoCentralFoam as it comes to shock waves.

In case of the forward step : why the boundary values are 3 m/s , 1 Pa , 1 K ? Why do we have to use Ma instead of , let's say , 350 m/s , 1e5 Pa and 300 K ? Why the results file has only values for rhoUx,rhoUy,rhoUz,rho and not for Ux,Uy,Uz,e?

Thanks

Hi
I read before somewhere that the values have been normalized(I can't remember by which values) but its only a simple example too see the solver works(even not very precise results) or not not more.:D
you can change all values.feel free and see it.
