Taking a closer look at how the Krylov evolution works, I noticed that it may be computationally inefficient. A small study of this is done in the script below [1], which executes nonequilibrium dynam…

I've run into some problems using all of the Runge-Kutta algorithms (purely explicit, EDIRK, and SMR91) with a 2D turbulent channel case. Using a convective CFL of around 1, I can advance through tim…

Hi there :)
I want to solve many ODEs which involve a small parameterised convex QP problem as a part of evaluating the right hand side. The QP is of the standard form:
`min_x x' Q x + p' x`

One reader shared some helpful suggestions about some post-processing techniques that can be used to obtain other information from the accelerometer data.
Examples:
- Position
- Velocity

With `ControlSystem` we were attempting to build the stack towards doing nonlinear optimal control, but we found that having a separate `ControlSystem` type is the wrong way to go about doing it becau…

Ann suggested that we modify Langevin_evolution to return source terms for the fields so that we could try higher order Langevin time integration methods like Runge-Kutta, as John pointed out.
We d…

I'm not sure this branch is doing anything:

It might be nice to have (Julia) implementations of the classical collocation schemes. Up to now, only some Radau and Gauss methods are available (as far as I know; some in `ODEInterface` and others `…

It would be very nice to have (pre- and) post-stage callbacks, similar to [PreStage](https://www.mcs.anl.gov/petsc/petsc-current/docs/manualpages/TS/TSSetPreStage.html) and [PostStage](https://www.mcs…
