hi
I'm try simulate semi close centrifugal compressor with cfx.
first i import my blade to bladegen then mesh in Turbogrid and setup in cfx-pre(Turbo mode) az below:
element number about 300,000 and
basic setting
1-steady state
component
2-22000 rpm
3-physical time scale 0.0002
4-tip clearance at shroud : yes
boundary condition
5-air ideal gas at 25C
6-relative pressure 1bar
7-inlet: p total , outlet: mass flow rate
8-p in=0 bar , t in=20 C
9- mass flow rate=0.2 kg/s per component
and for final step run it in cfx-solver and after several step solver stop and error message show up
"The ANSYS CFX solver exited with return code1.No results file have been created."
what happen and what i should to do??
before post this thread i read http://www.cfd-online.com/Wiki/Best_...omachinery_CFD
