From the Gitter discussion:
- [x] 1) Periodic. You just wrap around the vector when the coeffients flow over. This is not a banded matrix, so BandedMatrix(L) should error there.
- [x] 2) Dirichlet…

In the PDE concept, the general layout is as follows. The structure has a list of (quadrature) cells. The only function of these cells is the integration, thus attached to each cell is an integration …

I discussed with Randy about this today. But does anyone know why we arrange cell data in an array as q(nvar, mi, mj, mk) instead of q(mi, mj, mk, nvar)?
To me, the first approach, which we are usi…

I just came from a meeting where I met a mathematics professor who specializes in ODE's. When I showed him FOODiE, he commented that the algorithms are not state-of-the-art and that he would not use …

@mauro3 brought up a good point that the scope of DiffEqBase may not include PDEs. I think this is a good point because:
1. The interface on ODEs (ODE, SDE, DAE, DDE) is pretty clear given what we …

Hi Chris,
Wally here, just leaving a message per our discussion earlier to get the conversation started on the project to link DifferentialEquations.jl with Stan. What should I be reading up on as a …

During construction of sparse matrices and when using `setindex!`, entries with values `0` are not included/dropped from the underlying storage. This is no good for certain applications. In particul…

This project will make use of the Finite Element Method for solving PDEs. [Here](http://sfepy.org/doc-devel/index.html#) is a python package that does this for us, leaving us to just state the problem…

As discussed in https://github.com/JuliaDiffEq/Roadmap/issues/5, we have set out for the DAE types something like `DAEProblem` for ODEs defined by an implicit function `f(t,u,du,resid)` where `resid` …
