It's a little subtle -- during the simulation, the subgrid viscosity will be calculated on the grid, where it should be non-negative, and immediately multiplied by the other terms to...

Yes any pseudodifferential filter (multiplication in coefficient space) is pretty easy to implement.

I ran into the same issue. For me, deleting the local `sheets.googleapis.com-python.json` file, running my script again, and reauthenticating through the printed URL fixed things.

No, we still need to work around the lack of higher-precision support on apple silicon for spherical problems. But for Cartesian problems I expect everything to work fine. But that...

@gmvasil just found this, might be useful for writing true arbitrary precision routines for the jacobi stuff: https://github.com/c-f-h/flamp

General Functions are added to v3 with #227.

Added in d3843a7.

Thanks, we have a separate issue #221 to remind us to add examples/docs on this.

Doing this correctly for general PDEs is still an open research problem, but we're working on it (see this [recent paper](https://arxiv.org/abs/2211.17259)), and there will be a separate release and additional...

This issue is that, like all Dedalus models, enforcing boundary conditions requires tau terms, and these get complicated when you have different boundaries meeting at edges/corners. We understand how to...
