There is a Julia package called Grassmann.jl for doing computational geometric algebra.
The example of writing Maxwell’s equations in terms of geometric algebra \[ \nabla F = J \] makes me wonder if this is a better way to solve Maxwell’s equations numerically. I found one thesis on this topic already.
