Compressor X is operating at a non-dimensional flow greater/lower than the entered data

A Warning message in AFT Arrow

There are two variations of this Warning:

  • Compressor X (Junction Name) is operating at a non-dimensional flow greater than the entered data.

  • Compressor X (Junction Name) is operating at a non-dimensional flow lower than the entered data.

The listed compressor junction is using a Compressor Map, and the final solution had a non-dimensional mass flowrate that was higher than the Stall Line or lower than the Surge Line. Therefore, the operating point is outside the range of the Compressor Map, and the solution may have some uncertainty or error.

This Warning is similar to the Warning about non-dimensional speed. This Warning (about flow) describes the left/right boundaries of the Compressor Map.
