• Clawpack: base level 170x140 cells with 3-4 more levels, (x,y)[(-.005,.08)(.0,.07)], max cfl 0.9
• WENO-TCD: base level 340x320 cells with 4 more levels refined 2,2,2,2 times respectively, (x,y)[(-.005,.08)(.0,.08)], max cfl 0.85)
• The "normalized cost/timestep" is adjusted for the differing base grid resolutions
