The way error control is handled by the current implementation of the runge kutta variable stepsize integrator is not correct.
The implementation uses the relative error and the higher order estimat…

This came up in #177.
> The memory consumption of `SSPRK22`, `SSPRK33`, `SSPRK432`, and `SSPRK932` could be reduced by removing `tmp::uType` in the corresponding caches. However, this temporary sto…

@ranocha tasked us at first with fixing memory usage in https://github.com/JuliaDiffEq/OrdinaryDiffEq.jl/issues/178 . We now have all of the pieces in place to do it correctly (see https://github.com/…

Hi all,
I am a second year PhD student in mechanical engineering at UC Davis studying numeric methods for optimal control. I just learned about dask and I'm excited about using it for the types of …

**When there's a 0 value in the interval between x0 and xn, graph breaks.**
This happens because there's a division by x while calculating C-constant for exact solution.
**Graph breaks because of …

I am running Ubuntu 16.04 LTS.
I just completed fresh installs of Anaconda (python 3.6.6) and brian2 (v2.7) into a brand new anaconda environment. I ran brian2.test() after install and was confron…

This is to propose to support the API PETSc uses for its ODE/DAE solvers.
I think the PETSc framework is the nicest around and the most modern (afaik).

DiffEq's first PDE attempt (which started the package) was a failure. The issue was that it was tied directly to an FEM subpackage I made internally, but then it couldn't scale to all of the problems …

Hey,
This package has really evolved and looks really cool! I was thinking it would be nice to add common interface bindings. To do this, it would just need to add a dependency on DiffEqBase and im…

@wenegrat and I talked about implementing a `split viscosity' method for stabilizing time-stepping.
Essentially, we would like to allow the user to specify some constant 'spliting viscosity' (or d…
