supersonic inflow bc

jentink · November 29, 2017, 11:29

I am trying to run a problem I ran with version 3 awhile ago. My freestream pressure is 5640 Pa, but when the problem runs, it says my freestream pressure is 1089. And my velocity is 3x what it should be.

here's my bc:

MARKER_SUPERSONIC_INLET= ( freestream, 217.0, 5640.0, 1499.0, 0.0, 0.0 )

Hi Tom,

the freestream values that are printed at the beginning are computed using the Mach Number and the Reynolds number you specified. They are only used for initialization, for the MARKER_FAR option and for non-dimensionalization. So it is independent of what you specify with MARKER_SUPERSONIC_INLET.
