ScalarWaveFVM.jl is a numerical framework for computing the scalar self-force in general relativity with finite-volume methods. The project is designed around symmetry-reduced formulations of the wave equations, robust evolution near singular source structure, and numerically stable flux-based discretizations that can support precision self-force calculations on curved spacetimes. It serves as a research code for exploring both the physics and the numerics of self-force problems.
The code treats self-force evolution as a flux-based problem where local conservation and stable handling of sharp source structure matter more than relying on a purely formal high-order stencil. That makes the method a good fit for difficult curved-spacetime wave evolutions.
ScalarWaveFVM.jl is not positioned as a generic PDE sandbox. Its architecture is aimed at precision scalar-wave evolutions in general relativity, where coordinate choices, source regularization, and stable numerical fluxes have to work as one system.
