    The job stops because of an error in the "Stagnation pressure" boundary condition setting.

    It looks like you've set the Physics to use a two-equation turbulence model, and specified the inlet as Stagnation Pressure. In that BC setup panel, you then need to click the 'turbulence' icon and define the turbulence parameters.  By default, it's probably Turbulence Input Type = Auto; Turbulence Intensity Type = Auto, and Turbulence Flow Type = Internal.  For that combination you need to define a non-zero value for 'Turbulence Velocity Scale', which was missed for this run.  You can also change the settings for those other parameters to fit how you want to define the incoming turbulence at that stagnation pressure inlet.
