prandtl-meyer expansion wave
 

i have difficulty in setting up boundary condition of prandtl-meyer expansion wave contained in prof. anderson's book. is the fact, that velocity vector should be parallel to the wall, included directly into the code ?

Re: prandtl-meyer expansion wave
 

is abbett's formulation a just correction for accuracy or necessity for a reasonable solution ?

if the latter is right, can we still say that we got a result from cfd ? isn't abbett's condition derived from an analytic solution ?
