(21/9/2019) This includes the inlist and mod file for the simulation for our publication "Pulsational Pair-Instability Supernova I: Pre collapse Evolution and Pulsational Mass Ejection" (submitted to ApJS, available in arXiv preprint by arXiv:1901.11136). The included file "inlist_prepulsation" constructs a sample He-star for a specific mass until it starts pulsation. The inlist file "inlist_explosion" runs the model given by "inlist_prepulsation" for the dynamical part of the pulsation. "xini2.dat" provides the composition of a pure He-star for "inlist_prepulsation". The initial profile is given by "M140_Z0004_Omega0.mod". The run_star_extras.f is a cleaned and documented fortran90 file for instructing the code to switch on mass loss when the shell has a velocity exceeding the escape velocity and switch off otherwise.
