This test case checks the cool wind, hot wind capability by evolving a 7 |Msun|, Z=0.02 metallicity model from the zero-age main sequence to core helium depletion.

This test case has 1 parts. Click to see a larger version of a plot.

* Part 1 (``inlist_hot_cool_wind``) loads  a 7 |Msun|, Z=0.02 metallicity, main sequence model. A Reimers_scaling_factor = 1 cool wind above Teff = 8000 K and a Vink_scaling_factor = 1 hot wind above 12,000 K is enabled and the model evolves until the central helium mass fraction drops below 1e-6. At this point the mass is 6.75 |Msun|:
