from SU2 config_template.cfg


% Free-stream velocity (1.0 m/s, 1.0 ft/s, default)
FREESTREAM_VELOCITY= ( 1.0, 0.00, 0.00 )


I dont understand this number. Why is it a triplet of velocities?
I thought freestream is already given by the MACH_NUMBER?


[edit]
oh! i think i understand the triplet now.
this must be the velocity in the X, Y, Z direction for if the wing is set at an Angle of Atack and Sideslip.
ugh,.. why should we have to set this in config,... SU2 ought to auto calculate these values when there are angles given in AOA and SIDESLIP_ANGLE
