Apply limiter/upwinding to both X and Y advection
Seems to work better for neutral perpendicular diffusion than MC.
Take field (Nn, Pn, NVn) and Dnn separately; only upwind the field, and use cell face average values for Dnn. Also add neutral_conduction switch.
target settings used in SOL and PFR regions, rather than SOL and PFR settings.
Seems to help with smoothness of profiles
Same as anomalous_diffusion, obtain flows in X and Y for output when diagnose = true. Note: Only saves perpendicular flux, not parallel flux.
- For debugging purposes
- added setting for pressure floor. Added temporary debug flags for using floored Nn and Pn in DnnNn and DnnPn calculation (otherwise they could unbalance and lead to density loss - need more testing). There is a secondary floor which kicks in at zero gradient, this is now linked to the primary floor (but 2 orders of magnitude below).
- Seems to make energy imbalance less imbalanced, but I haven't gone through the maths yet
Upwinding and limiting with MC/MinMod are causing checkerboarding and/or crashes in the neutral_mixed example and provide seemingly no benefit in production runs. Reverting to original operator but with added flow diagnostics. Left warnings on the other operators, maybe we'll get back to them at some point.
