Resolution Tests

The idea here is a bit different than adjusting data file parameters to see what works best. Here, I am simply lowering the number of levels while keeping the number of processors constant. This is to see how having a larger root grid might help performance when running on many processors.

There is density gradient refinement to level 3, and cooling time threshold refinement to level 7 (based on fiducial run). qTolerance changes for each run to keep this consistent. For example, the level 6 run has

qTolerance = .25, .40, 1d30, 1d30, ...

so that there is the same refinement criteria at the same effective resolution. For level 5…

qTolerance = .40, 1d30, 1d30, 1d30, ...

The level 4 and level 3 runs have the same qTolerance…

qTolerance = 1d30, 1d30, 1d30, 1d30, ...
