- WENO-TCD - 300x240 base grid 2,2,2,2 refinefinement, cfl max 0.85
- "cost/timestep" = integration time / coarse level timesteps
150x120 base grid
Method | whole time | integration time | time steps | cost/timestep (sec) | 1/2*(cost/timestep) (sec) |
Roe- Min-Mod: inviscid, (150x120 base grid 2,2,4,2 refinement, cfl max 0.9) | 3221 | 494 | 290 | 1.7 | 0.85 |
Roe- Min-Mod, (150x120 base grid 2,2,4,2 refinement, cfl max 0.9) | 5604 | 967 | 495 | 2.0 | 1.0 |
Roe- van Albada, (150x120 base grid 2,2,4,2 refinvimement, cfl max 0.9) | 6946 | 1627 | 518 | 3.1 | 1.55 |
Roe- van Albada: 2x Refined, (150x120 base grid 2,2,2,2,4 refinement, cfl max 0.9) | 24607 | 8388 | 545 | 15.4 | 7.7 |
- Note: To compare the 150x120 base grid results with the 300x240 base grid results, the 150x120 "cost/timestep" can be divided by 2 to include the extra 2x refinement that makes the finest grid scales equivalent.
