[Mesa-users] entropy relaxation skipped

Hi all,

I'm trying to relax composition and entropy for a white dwarf model. The profiles come from hydrodynamic simulations with a Helmholtz EOS without coulomb corrections.

composition relaxation occurs just fine. However, my problem is entropy relaxation. In the terminal output file I've attached, MESA tries a few times with entropy relaxation and gives up instead of the usual timescale reduction to the minimum timestep. Does anyone know why this might be occurring?

Also attached is a comparison of the entropy profiles pre-relaxation (default) post relaxation (relax363) and the target profile (from hydro simulation)

Thanks,

Akaash
