[Mesa-users] r_center not changing in inlist_infall

[amar at aries.res.in]

Dear mesa-user team, 

I am trying to produce a stripped progenitor having ZAMS mass of 25 M_sun. I imposed the condition envelope_mass_limit = 0.01 along with mass_change = -1d-3 in inlist_remove_envelope to produce a stripped progenitor. The model could successfully evolve up to the stage of Fe-core infall indicated by the termination code ' fe_core_infall_limit '. The stripped model has a mass ~ 7.4 M_sun at the stage of Fe-core infall. 

Further, I used the final.mod file generated at the end of the evolution and tried to evolve the shock using the ccsn_IIp directory. But the model continues to run (Ran more than 100,000 steps) without converging and no change in r_center is seen. What could be the possible cause for this situation. Any help to evolve the model further shall be highly appreciated. 

OS : Centos 
mesa version : mesa-r21.12.1 


With regards, 
Amar
