Hi Siyi,
In principle this is possible. Even in the best case, it will probably
require some significant (re)writing of code. How much, and how difficult,
will depend a lot on what you want to do. Some initial questions to narrow
down your requirements:
* Do you want to use this in 1T or in 3T (or RadFLAH?) simulations?
* Do you Nele / ZBAR depend on only (density,temperature,composition),
or on additional independent variables? (maybe including time /
history?)
* Do you just want one Eos implementation for all of your material(s),
or do you want an implementation that models just the behavior of the hydrogen
fraction in a multi-material, multi-type situation and can be combined
with other implementations for other materials?
* Do you want an Eos that is thermally ideal or something more
complicated?
* Do you need the derived quantities that Eos can potentially
provide - see Eos.h - and if yes, which ones, or would you be satisfied
(at least initially) with just getting the main variables
like EOS_PRES, EOS_EINT, EOS_TEMP returned correctly by Eos?
