This test suite example checks the accretion of material and angular momentum onto a 20 |Msun| model.


This test case has two parts. Click to see a larger view of a plot.

* Part 1 (``inlist_zams``) creates a 20 |Msun|, Z=0.02 metallicity, main-sequence model.

* Part 2 (``inlist_accreted_material_j``) continues the evolution by first applying uniform rotation Omega/Omega_crit = 0.1, and then accreting material with the same composition as the outermost cell at a rate of 0.001 |Msun|/year with an angular momentum of 0.1 Keplerian. The model terminates when the mass reaches 25 |Msun|:
