Research direction
Start by reviewing the existing state.xn component and the auxiliary composition implementation, especially how RHS and Jacobian support are defined. Determine which component interface can represent state.rad without aion, zion, EOS coupling, or 0–1 bounds. Done means a documented implementation path is agreed for evolving radiation energy density with state.xn and T.
Written by the indexing model from the issue text.
Description
To implement a photoionization network, we will need radiation energy density as a state components, call it state.rad. It has a RHS (ydot) that depends on T, state.xn, and state.rad, and it should evolve along with state.xn and T. However, it differs from state.xn in three different ways:
- it does not have aion and zion;
- it won't affect the EOS
- it's not limited to 0 -- 1.
Is there an existing component that can work this way? Any suggestion on how I should go about adding this new component?
It seems to me that the auxiliary composition won't work, because it does not have a RHS and Jacobian, but I might be missing something.
