 July 5, 2004, 03:14 Multi-Block interface treatment using FDM scheme! #1 Kyung-Seok, Kim Guest   Posts: n/a Hi, Everyone~ I'm a beginer in CFD field. I need your HELP. My Problem is the below. 1) 3-D Problem, using Finite Difference Method(FDM) 2) 2 Block used (i.e Multi-Block) ---------- 1st block ---------- 2nd block ---------- 3) The bottom face(grid) of 1st block and the upper face(grid) of 2nd blcok are NOT matching each other! Q)How can I treat this grid mis-matching problem ?

I think that your reference(you give me) is about FVM(or cell-centered scheme).Right? But I use FDM scheme, so it's a little bit different. I want to know.. How can I transfer "Potential information" in Non-Multiblock interface ? Let me know any reference or book or anything... Thank you in advance !
