[Mesa-users] Trying to inject energy into a star

[Aaron Dotter]

Hi Yotam,

Have a look at mesa/star/test_suite/envelope_inflation/

Try running the test case and reading src/run_star_extras.f.

It uses the "other_energy" hook provided by MESA and the array x_ctrl(:)
which is accessible from the &controls inlist to input the parameters.

Cheers,
Aaron
