[Mesa-users] How can I insert mass to the core of the star

[Bear Ealeal]

Hi,I want to simulate destruction of a planet near a core of a giant star, for that I need to insert mass not in the envelope. When I insert energy I can determine where I do it, is it possible with mass?Thank you very much for you help,Ealeal
