XRB Paper Data/Progress - Newest 0.5cm Run from NY Blue using FL87 burner

This run is set up as the original 0.5cm run on nyblue except here we are using a burner based on the Fushiki and Lamb (1987; PDF) triple alpha reaction rate. This run does not contain an artificially evolved adiabatic region.

Some runtime statisitics for this run on the BG/L racks of NYBLUE at BNL are generated from this bash script file:

cmalone@fen:>./get_run_info.sh 5*.out

Number of cpus: 256
Total time: 480867 seconds
Number of timesteps: 104334
Average time per timestep: 4.60892 seconds
Total number of cpu-hours: 34195

Below is the temporal evolution of the maximum enucdot and its location.

Below is the temporal evolution of the maximum temperature within the He4 layer and its location. Note that because we define the He4 layer to be where X(He4) > diag_define_he_layer (default = 0.1) and because we have convective undershoot that is dragging He4 deeper in the atmosphere, the location of max(temperature) changes quite a bit.

In light of the above discussion, I think that using max(temperature) as a diagnostic is not very enlightening while we still have the convective undershoot problem. I'm currently working on setting up a model that is "more convectively stable" in the zones just below the helium interface.
