About the simulation codes

We use the 1D stellar evolution code MESA and 3D hydrodynamic code PPMstar.

MESA is an open source, 1D stellar evolution code developed by Bill Paxton and collaborators (Paxton et al 2011, 2013, 2015). We used it to produce an initial condition for the 3D hydrodynamic model. PPMstar is a proprietary, 3D hydrodynamic code primarily developed by Paul Woodward. It is based on the PPM and PPB advection schemes. A recent version of the code was described by Woodward, Herwig, & Lin (2015).
