With #219, multidimensional NCCs are supported in Cartesian domains, allowing for multidimensional LBVPs, EVPS, and NLBVPs. Additional multidimensional NCC implementations are being tracked in #188.

Hi Chris. I wouldn't put too much effort into understanding the manually entered tau terms -- we have a new system that automates this programmatically and should be much easier...

Daniel is currently going through and updating most of the examples to use the new LiftTau structure (in the [d3_examples](https://github.com/DedalusProject/dedalus/tree/d3_examples) branch). There are a few examples that still need some...

We now have narrative documentation on how to implement [gauge conditions](https://dedalus-project.readthedocs.io/en/latest/pages/gauge_conditions.html) and [tau terms](https://dedalus-project.readthedocs.io/en/latest/pages/tau_method.html) directly in the problem formulation. Please feel free to reopen for further discussion if anything is...

Yeah EVPs can be more sensitive to the tau choices. But here I think there may be some other things. First, the variables in the EVP are implicitly multiplied by...

Looks good. Only issue I can think of is that this could be misleading if we save vectors or tensors in coeff space, since there the coefficients may correspond to...

Yeah or maybe just `{-1, 0, +1}` or even `{-, 0, +}`, and you have to know its spin or regularity based on the context? Any thoughts @lecoanet?

@jsoishi want to push this to a separate branch on the main repo?

Marking as a draft since we're still WIP.

Good catch. I think you're right that we want to just cast up here, but we have to be careful since we probably want it to still fail on the...
