Hi everyone,
For circuit board EM simulations below 100 GHz the substrate dispersion in other simulators is often modeled using a wideband Debye model (a.k.a Svensson/Djordjevic model). As that mod…

Is there a way to convert a `LinearOperator` to an explicit **sparse** matrix representation.
So a sparse equivalent of the `todense()` method that returns a `scipy.sparse.csr_matrix` instead of a …

Dear MFEM team,
first we want to state that we are truly impressed by the scope and amazing quality of your library, which has already established itself as a major framework for the development, a…

I've been driving (myself batty) around the intersection of economic networks with social processes for discussion, deliberation and decision. In doing so, I keep feeling that there's a significant r…

Dear MFEM Developers and other Community Members,
I was trying to write a program that solves typical Maxwell's equations in a nice domain. Unfortunately, the errors don't converge to 0. I have ref…

For dense plasmas, it would be useful to have binary particle collisions implemented.
Here are a few references that could be useful:

Hello!
The next 6 months I will be working on the design of the ionization stage for a micropropulsion system and I'm trying to find the ideal open-source code to simulate the model of an hollow cat…
