Hello all,

I have a simulation to run at varying Knudsen numbers.

I have used the wedge15Ma5 tutorial file as a starting point and managed to get it to run with a modified geometry and mesh. I have selected a Mach number of 5 for my simulations and wanted to modify the Reynolds number to achieve Knudsen numbers of 0.1, 1 and 10.

I do not understand however how to vary the density in the simulation. I tried modifying the number of particles in the dsmcProperties dictionary, but that only seemed to change the stability of the simulation.

Could somebody indicate me the correct way to do this?

Thanks in advance.
