[mesa-users] Interacting with EOS module

[Michael Zingale]

Hi, I don't have the answer for you, but instead a caveat.  We put the MESA
EOS into our hydro code, but in the process we found that not all of the
EOSs that comprise the MESA EOS return all of the derivatives.  In the end,
we wound up having to restrict ourselves to just using the helmeos in MESA
(which we were using originally anyway), because that was the only one that
had all of the derivatives.
