Thought I would just formalize the feature request before someone beats me to it. The abundance expansion shouldn't be too difficult although if the goal is to stay away from 3rd party libs both imple…

## Describe the bug
When using the dictionary input to coordinates it can change the precision of the resultant coordinates function. This was seen during some of the neutronics work. It is sides…

## Bug Description
If a PDE does not have a time derivative (say the mass equation for incompressible Navier-Stokes), then you will end up solving, for that sub-vector of dofs, the equation: residual…

The good news: we now have a working class that gives O(N_nonzero) instead of O(N) performance. This could be a big deal for https://github.com/libantioch/antioch sensitivity applications where our e…

Wanted to start a discussion / propose a new feature: ex-core structures in ARMI
The base system I'd like to model is one or more concentric right cylinders defining ex-core structures like core ba…

## Bug Description
When running ```openmc.deplete.get_microxs_and_flux``` with a geometry that uses dagmc the dagmc h5m can't be found by the get_microxs_and_flux. I believe this is because get_mic…

## Reason
I made a simulation mistake that I think other neutronics-focused researchers could also easily make and wanted to add some documentation / change the tutorial to prevent this. Essentially,…
