Hi @aragilar , our scikit-odes tests are now failing (see the mentioned issue above), is there any progress with the switch to meson or should we skip the scikit-odes tests...

Thanks!

Have you come across [`MethodOfLines.jl`](https://github.com/SciML/MethodOfLines.jl)? It doesn't do everything you list here yet, but I think it's all within scope. @xtalax

What's needed for this? Something else blocking or just a case of writing the function? If the latter case, I could try to do it I would like to use...

So using that isapprox? Or is there a cleaner way?

I like PDEFiniteDiff.jl better but is the jacvec stuff limited to finite diff or more general?

Haven't tried this locally yet but the order of your independent variables (currently `A(x,y,z,t)`) might need to be the same as the order in the BCs (currently `A(t,x,y,z)`). We need...

Another thing is I don't think you can specify 2nd order (in time) systems yet, so you might need to explicitly rewrite it as a first-order system for now, but...

`Dtt(u) ~ f(u)` --> `Dt(u) ~ v, Dt(v) ~ f(u)` (and make `v` a new variable with same dependent variables as `u`)

Looks like the problem could be broadcasting the `~` when defining your eqns. I don't know whether this is supported. Could you define your equations one by one in a...
