(*http://www.cfd-online.com/Forums/main/84683-ripples-free-surface-boundary-condition.html*)

RIPPLE's free surface boundary conditionIn SOLA-VOF's code,the pressure in surface cell is interpolated by neighbouring fluid cell with a variable 'PETA'. In RIPPLE, a improved method 'CSF' replaces the free surface pressure condition, and i cannot find 'PETA' again.
My question is:does RIPPLE still use interpolation to obtain pressure in surface cells? if not, how can i get it? Thanks. |

boundary conditionSee http://math.rug.nl/~veldman/publications
DeJong-afstudeerferslag.pdf and other articles and dissertation. if you have RIPPLE source code please send it to me. My e-mail: vs198080@mail.ru. I am try understand pressure boundary condition. I have SOLA-VOF, VOF-2D, VOF -3D source code. |

Hi ves
Thank you for your reply. but i have no RIPPLE's code either, and your adress is invalid. Along |

This link is work. This page have links for aricles and PhD, see Gerris PhD , Kleffsman PhD, and DeJong article. It is explained pressure Poisson boundary condition for projection method solving Navier-Stokes equation (this metod used in RIPPLE). RIPPLE User Manual have not information about pressure boundary condition, but in above works used coefficient peta same as SOLA-VOF. By means of this coefficient PETA coefficients of the Poisson equation are calculated. I developed the software based on above works, SOLA-VOF, Veldman sample program (not free surface), but pressure calculation wrong. Why? I do not know. Veldman page consist samle and lecture. |

Thank you for your help. This is my first time contact with Veldman sample program, what's the problom with your pressure calculation? can you tell me the detail? Along |
