BUG: forceCoeffs: Log entries of pressure and viscous components are swapped
Summary
Reported by: @THO
Here an example:
OLD Behavior
forceCoeffs forceCoeffs write:
Cd : 0.8975191254 pressure: 0.8568458762 viscous: 0.04067324918
writing force and moment coefficient files.
NEW Behavior
forceCoeffs forceCoeffs write:
Coefficient Total Pressure Viscous Internal
Cd: 0.8975191254 0.04067324918 0.8568458762 0
As you can see, pressure
and viscous
are vice versa compared to the old behavior and for external aerodynamics, the main part is the pressure
contribution. Hence, there is some mistake either in .y()
and .x()
or the output should be changed from:
Coefficient Total Pressure Viscous Internal
to
Coefficient Total Viscous Pressure Internal
