Oct 1, 2024Concise monthly summary for 2024-10: Fixed a critical bug in the IPPL-framework/ippl project related to load vector computation in Lagrange spaces (interpolation of the source function). The fix ensures the RHS load vector is properly assembled by interpolating the charge density field over the basis functions, introducing a temporary field for intermediate calculations, and cleaning up unused code paths. Tests were updated to populate the RHS via the sinusoidalRHSFunction to validate the interpolation path. Impact: Improves accuracy and stability of the RHS assembly in interpolation-based computations, reducing numerical errors in load vector evaluation and enhancing solver reliability for simulations built on Lagrange spaces. This directly supports more trustworthy simulation results and smoother convergence. Context: IPPL-framework/ippl repository. Commit: 9afa5b25e0d9139dbdae05fd6745fb86611798f3 - "change RHS to have interpolation for the Load vector computation".
