Results
RUN#1 (Oct 15 2003)
Linear wave with A=10^{-6} and w=1 initially at (0,0,0) with Geodesic slicing
Resolutions: Level-1(h=0.25), Level-2 (h=0.125), Level-3 (h=0.0625)
Grid Extent (along x-axis): Level-1(8--16), Level-2 (4--8), Level-3 (0--4)
- 3-Level FMR with LINEAR GUARDCELL FILLING and NO REFLUXING: gzz (z=0) Notice junks coming from the interface!
- 3-Level FMR with KO-QUADRATIC GUARDCELL FILLING but no REFLUXING: gzz (z=0) Notice reduced interface junks!
- 3-Level FMR with KO-QUADRATIC GUARDCELL FILLING *and* REFLUXING: gzz (z=0) Notice reduced interface junks!
