Compressor X is operating at a non-dimensional speed 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 speed greater than the entered data.

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

The listed compressor junction is using a Compressor Map, and the final solution had a non-dimensional speed that was higher than the data entered for the Compressor Map. 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 flow. This Warning (about speed) describes the top/bottom boundaries of the Compressor Map.
