Section dependent isotherms and alternative approaches

[alters]

@Flynn

This should be possible. Relevant fields to check are: write_solution_last_unit (or write_solution_last). This will write the state vectors at the last time point to last_state_y in the output group and time derivatives to last_state_ydot. Appending last_state_ydot to last_state_y gives the final vector that can be passed to the next simulation through the init_state in the input group.

This is actually something @j.breuer and I were discussing recently. I need to follow this exact approach to solve a dilemma described in the earlier post (Protein at inlet not showing up at outlet - #10 by Flynn). We were not able to figure out a solution (Jan mentioned there might be a problem with consistent initialization). I still have those hdf5 files lying around, so we could look into actually solving the problem again. To be honest, it was a highly atypical application of CADET and using a workaround with running simulations sequentially is totally fine. The ultimate outlet solution already requires three separate simulations, before we implement the workaround.

I have another application on the docket that also requires using section-dependent isotherm parameters, so I am interested in the outcome of your investigation @Flynn.
