The filenames are of the form: 15_14p80_0p05.awa 15_14p80_0p05.dat 1) 15 is the zero age mass. 2) 14.80 is the current mass. 3) 0.05 is the metallicity relative to solar. 4) .awa is the input file. 5) .dat is the MERGESPEC file. There is one case where the naming is degenerate - 10_9p99_0p05 - in this case the second model has _1 added to the filename. Because the models crashed for a few grid points I made these changes to the original grid: MODEL PARAMETER GRID USED (WHY CHANGED) 100_96p50_0p05 Teff 48498. 48500. (Crashed) 30_27p43_0p05 Teff 29727. 29730. (Error in out.txt) 10_10p00_0p05 logg 4.250 4.255 (Crashed) 5_5p00_0p05 has no results as there were no wind parameters. Fabio suggested dropping this model. 30_15p62_0p05 is also not included. The model *immediately* crashed. After varying all the parameters, the only solution I found was to increase alpha from 0.293 to 0.33. The model then ran, however an error message was produced in the output file.
