Hi there,
I'm working with collocated grid, and i'm concern about the conservation error coming from the pressure term. Morinishi et al. (JCP 143, 90-124, 1998) pointed out that these errors are dissipative and thus the collocated grid may be stable althought affected by conservation error!! So my question is, are these errors always a sink, or for some cases it might be a source?? If you know some publication addressing this topic please let me know! Sincerely, Frederic Felten. |

May I ask for a bit of clarification since I do not have the reference cited.
Conservation error of what? Mass? Momentum? Energy? Dissipating what? What terms are you introducing that depart from symmetric differencing of the governing equations? |

hi andy,
The pressure term has a conservation error in the transport of kinetic energy. I could send you a copy of this article, for you to be able to understand the full problem. Just email me at feltenf@hotmail.com Sincerely, frederic Felten |
