Hi everyone,
I´m working on a multiphase problem on CFX and I've noticed that there is an option to use "interface compression (default value=2)" for free surface problems. There isn't such information on CFX manual, even a citation. I've also looked for in forum, but apparently anyone knows too. Does anyone know what this option does on fluids interface? I´ll be glad if anyone explain this for me, Willian |

Sometimes these are documented in the release notes for the CFX version it is introduced. You might have to go back a few versions to find it. Otherwise talk to CFX support.
But I would just try it and see if it improves things. If it does not improve things then revert to the default. |

Quote:
"Interface compression level for interface sharpness, where 0=none, 1=standard compression, 2=enhanced compression. This helps convergence, but increases cost." "The default for "Interface Compression Level" has been changed to from 1 to 2. The new default is often helpful to improve interface sharpness." I still don't know how exactly it works, but I'll try use it and see if it changes anything. Anyway, thanks a lot for your helping Gleen! Willian |
