Hi everybody,
I want to start a 2-phase flow in CFX-4 restarting from a Single phase dump file.
Two different things are happening to me. If I restart from dump not setting an initial guess for volume fraction, solver tells me that it doesn't sum 1 for every cells. However, if a restart from dump file using initial guess for Volume Fractions, solver tells me the following message extracted from output file:


---------
..INLET BOUNDARIES
....PHASE NAME 'GAS'
....PATCH NAME 'INLET'
....NORMAL VELOCITY 5.9536E+00
....VOLUME FRACTION 9.9605E-01
....TURBULENCE INTENSITY 3.7000E-02
....DISSIPATION LENGTH SCALE 4.0296E+00
..INLET BOUNDARIES
....PHASE NAME 'SOLID'
....PATCH NAME 'INLET'
....NORMAL VELOCITY 5.9536E+00
....VOLUME FRACTION 3.9500E-03
....TURBULENCE INTENSITY 3.7000E-02
....DISSIPATION LENGTH SCALE 4.0296E+00
..PRESSURE BOUNDARIES
....ALL PHASES
....PATCH NAME 'PRESS'
....PRESSURE 0.0000E+00
....STATIC PRESSURE SPECIFIED
..OUTPUT OPTIONS


THE PRESSURES AT THE BOUNDARY NODE BETWEEN CELL ( 1 1 5) AND CELL ( 1 1 6) IN BLOCK SOLID 11 ARE NOT THE SAME FOR EACH PHASE


TEN PRESSURE BOUNDARY NODE ERRORS HAVE BEEN DISPLAYED OUT OF A TOTAL OF 42
42 ERRORS IN SETTING REAL BOUNDARY CONDITIONS
THE CFX-4 SOLVER HAS BEEN STOPPED BY SUBROUTINE CMDBC

Well, what does that mean? SOLID 11 is the block where is located the INLET BC.
How can I procceed with it? Regards,
cfd guy

Try running without specifying the pressure boundary. With patch name "press", the code will understand that it is a pressure boundary with zero pressure.
