Dear friends:
I have implemented the SIMPLE algorithm on unstrutured grid. But when i implement the SIMPLER algorithm of algorithm.I met some problems about calculation of the source term of pressure equation. Since on the unstrutured grid, it is the face normal velcotiy contribute to the mass balance. How to compute the "Uhat" term for the face normal velocity. Could you pleaase suggest me some references or idears about this phenomena? Regards Your Sincerely |

I read this paper and it explains SIMPLER method in collocated grid very well:
"Improvement of SIMPLER Algorithm for Incompressible Flow on Collocated Grid System" by Y. P. Cheng a , T. S. Lee a , H. T. Low a & W. Q. Tao b and also "role of underrelaxation in momentum interpolationfor calcualtion of flow with nonstaggered grids' by S. Majumdar. they really helped me to do it. |

Chapter 7 7.3 calculation of pressure, Mr. Peric describes how SIMPLER is done in a pragraph. That is applicable to structured or unstructured meshes. Follow that. |
