Hello,

kind of hard to find a right topic for this.
I am currently trying to make a performance curve of a four-stage axial comrpessor. I have reference values of massflow rates which i need to achieve. The problem was that this setup has an average pressure at the outlet. So I needed to change the pressure and get hopefully the right massflow (kind of tricky but that should not be the focus right now).
Now I want to start new with a massflow at the outlet (like recommended in the CFX guide).
Is there a problem to use my current simulations with the ave pressure at outlet as initial value? Or does this only work when they both have the exact same BC? Cause last week when I started it quickly, there was an error. Do I need to interpolate something?

Thank you very much
