Hi every body



i,m working on a simulation with sonicFoam at mach=0.5.
it,s a cavity flow that vortex crash into the step, it has some kind of explosion and it makes pressure wave in my domain.


until right now there is not any problem, but at my probe pressure there are some noise behavior that is unwanted and i need to remove them.


my guess is that they are due the second order scheme that i use but i,m not sure about it.


any tips would be appreciated
