continuity convergence
Hi,
do you know how to fix convergence in continuity in modeling with vof (implicit)? |
Decrease the time step and try it.
Change grid. shk |
thanks for reply, i decreased the time step .. it still oscillates .. Unfortunatly i can not increase the mesh .. or cahnge..
what about URF, does changing URF, (radically decreasing it) leads to wrong results (even if reaching to convergence and low residuals) ? |
If "convergence" is achieved, it doesn't matter with which under-relaxation factor your simulation got there.
It will only take longer with low URF. |
