[Mesa-users] Possibly strange values of adiabatic compressability (Gamma1)

Hello everyone,

Many thanks for your replies.

As requested, here are some values at the location where Gamma1 is maximum
in an example profile:
logT: 7.335117
logRho: 3.043959
X: 2.039781e-07
Z: 0.01911058
abar: 4.058346
zbar: 2.029173
Gamma1: 1.727846
I have also attached that profile file.

I have also run the track again with eosDT2/ELM turned off (still using
r12115), and the behavior indeed seems to be much more normal (see attached
for an example profile).

Thanks for the help in resolving this issue.

Best regards,
Earl
