can we get the spatial discretization from MOLFiniteDifference somehow instead of xs = 0:Δx:ℓ each time?
Would be great to have sol.x
in the same way as ODE solutions have sol.t
. This means the prob
that gets returned from discretize
needs to save what mesh was used, then pass it to the solution. What's the best way of going about this? Could we make a new struct DiscretizedPDESystem
which subtypes ODESystem
and saves the mesh?
from methodoflines.jl.
@YingboMa would it be a bad idea to add array symbolic expressions x ~ 0:Δx:ℓ
as observed variables so that sol[x]
works?
from methodoflines.jl.
sol[u]
should do it. I think it might be broken until a few packages update though? @YingboMa

@YingboMa is this a bad idea?
from methodoflines.jl.
MTK doesn't really support array variables right now, and I think we should be careful on designing it.
from methodoflines.jl.
