All use "natural satellite" in their definitions, but natural satellite isn't defined. I've been using the terms "astronomical body" defined as: A material entity that is a natural resident space obje…

I tried using CUDSS.jl with a sparse matrix coming from an electromagnetism problem (using the FEM method)
The sparse matrix is stored in a JLD2 file that can be download here: ~~[https://github.co…

Hi @mlstowell @tzanio Recently, I'm working with the same problem in solving Maxwell's equation:
`Curl mu^{-1} Curl E - omega^2 epsilon E + i omega sigma E = - i omega J`
with a tetrahedral mes…

Hi!
I got a question about this Robin boundary condition for the curl operator in

# Parameterized quantities
I have identified 2 kinds of parameterized quantities.
## Same quantity name for different quantities
This kind of quantity shares its name between different quanti…

Currently the machinery should work for acoustics, which is a scalar equation. But we have not yet tested for any physics with a FieldDim > 1. Without a test case it is hard to see what to do. The ou…
