Hello everyone,
I understand that entropy filtering algorithms work well for excitation capture, see these two papers(10.1016/j.jcp.2022.111501),
but I don’t understand what is the difference between e-func = numerical/physical in the latest version of PyFr?
In my calculations, I found that when using e-func = numerical to calculate divergence, switching to e-func = physical allows me to continue the calculation, perhaps due to the presence of strong excitations in the flow field? (Mach number is 3 at this time)
Regards, Wgbb.
