[Mesa-users] Arbitrary heating in STELLA

[Jared Goldberg]

Hi Soham — 

Unfortunately there is not a simple way to do this without modifying the source code of STELLA, at least not in the public version packaged with MESA. 

You could potentially add heat in MESA and try to run until a bit later after shock breakout, depending on your intended application. 

Best,

I can only add heating due to decay of 56Ni at the moment., but would like to add an analytical or tabulated heating function. Thanks!
