Translate heat and particle fluxes from SOLPS B2 format to IMAS DD

[eldond]

I think these are defined at faces (double check with J. Lore), so we'll need #6 to fully support this work.

I don't know the difference between:

• fhex: Poloidal electron energy flux (W)
• fhetx: Poloidal electron energy flux [ fhetx ] (W)
  • This one sometimes has the word "total" in it, but how is the other one not total?

Also, edge profiles doesn't seem to have a heat flux field or any fields with units W.m^-2

• There are places to record fluxes like this in edge_transport.model
• For recording fluxes to walls, they can go in wall.description_ggd[].ggd[].energy_fluxes..., but it has lots of sub fields

[eldond]

We could read power from the core from b2.boundary.parameters and put it in IDS summary.heating_current_drive. We would have to make assumptions about how electron and ion power in SOLPS correspond to EC, IC, NBI, and other sources of input power or not care. We could also use power_additional and note the source as 'not specified' or something. Or make a yml file with instructions for how to assign power from boundary parameters into the summary IDS.

Do you have a sample SOLPS output dumped to IMAS?

Or perhaps you can take a look at the SOLPS-ITER source to see exactly how IMAS gets populated with SOLPS data.
