Proposed Changes

Give a brief overview of your contribution here in a few sentences.

The mass flow rate uses AxiFactor. The computation of axifactor in CIncEulerSolver::GetOutletProperties is inconsistent with GetAxiFactor in CFlowOutput.cpp, leading to a different mass flow rate used for the target mass flow rate boundary condition (reported as screen output) compared to the mass flow rate reported in the history file.
