PIC (particle-in-cell), space charge tracking simulation?

Perhaps the conversation is getting a bit narrow, but I’m hoping it will catch some attention and gather some momentum.

The FDTD method relies on the “staggered” (or nested) grids for the dual quantities. That works well when the grid is Cartesian.

The same outcome can be achieved with FEM grids via a careful choice of basis functions or choice of weak form.

So far I think there are very few alternatives to FDTD.

Personally I find these kind of topics fascinating and the scientific/numerical domain knowledge that people bring to the Julia forum is what makes it really interesting, not just another programming forum. So thanks for what you’ve posted so far; I for one appreciate it being posted publicly.

I’d also point out that discourse gives fairly powerful tools for people to mute threads they don’t find interesting.


I agree. In fact, I keep learning about new (to me) kinds of math and simulation by learning about Julia.
