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 …

I need to solve a time vary delay differential equations like this and I find dde() can only solve the const delay differential equation. The following code can not run.
```
using Plots

Dear All,
Galgebra does not seem to obtain the correct Christoffel symbols of the first kind; at least the values printed out indicate a skew symmetry, which is strange.
Starting with the metric…

(and make its subtypes also obey that)
This will allow dispatching on e.g. the state type of the integrator, which I used a lot in DynamicalSystems. I have opened some PRs to do this, but they will…

Hi @sdrave, @ftalbrecht, @renemilk! I think my `lti_sys_mor` branch is ready to be added here as a development branch. There are still some issues to resolve (like #285) and I would very much apprecia…

The notion of simulation model is used in many places in the specification, but the definition is very fuzzy. I improved the definition in Section 1.2 so…

Hi,
I would like to use a state derivative model that uses seven Unified State Model elements (USM7) in combination with the existing Tudat RK integrator.
@DominicDirkx informed me that the fact t…
