## Reason
A kernel means very many things, and even within MOOSE it means completely different things for Kernels and AuxKernels.
It ends being some sort of "common name" (or MOOSE-speak) for which…

Hi guys, I'm trying to figure out how to create a multivariate approximation to a nonlinear function `dfx`, but can't quite understand the multivariate interface. Below is an attempt at creating an or…

There is an issue with the description of the size of the BC Jacobian in the documentation. In the doc, the following is said for the size of the BC Jacobian:
> - dbc_dya : array_like with shape (n…

Some numerical schemes are _semi-implicit_, i.e., some terms refer to the new time step, and some terms to the old.
It would be good to be able to support such schemes in pymola. This could be done…

Introduce a mechanism how to make field output for given nonlinear iterations, i.e. multiple outputs per timestep. Can we trick the PVD file, or have this in separate VTK files?

### Description
When running the SSR algorithm, I notice that it always returns the first dynamic model it generates. This is, of course, in stark contrast to what the optimization behavior should b…

### Description
It is well-known that providing appropriate scaling values improves the robustness of iterative nonlinear solvers, see [paper](http://dx.doi.org/10.1145/3158191.3158192). Well-desig…

Hello,
I'm trying to convert a code I wrote in MATLAB to C++. It is about the dynamics of a structural beam. Because of the formulation, I naturally get a set of coupled ODEs in the form (already w…

Hello everyone. Could someone tell me is it possible to develop a solver for solving equations with solution dependent coefficinets or coordinate dependent coefficients? For example, in the heat trans…
