<div dir="ltr">Hello everyone,<div><br></div><div>I want to change TwoPuncture's code to add some matter to BBH simulation.</div><div>I think at first I should understand the method TwoPuncture used.</div><div><br></div><div>I have read two paper about this thorn by Marcus Ansorg <a href="http://et.al">et.al</a> and Vasileios Paschalidis respectively.</div><div>But I still do not understand how it treat the equation contains sources and a blackhole.<br></div><div><br></div><div>Another question, can TwoPuncture generate a spinning Neutron Star? I know it can generate BH-NS initial data. This question equal to "Is the source included Momentum Constraint has been writen to TwoPuncture's code?
