-
Effective one-body equations (Google Colab) -- An orbital mechanics integrator. Includes transfer learning solutions to increase integration time, hard boundary constraints through output transformations, and solutions with parametrized initial conditions as inputs.
-
DGP Gravity (Google colab) -- Testing a solver for waves in DGP modified gravity.
-
Inverse diffusion (Google colab) -- Testing a solver for the inverse diffusion problem (an ill-posed system of equations, so difficult to solve with traditional methods). Includes a basic grid search over some network hyperameters.
Files in this repository mostly contain scratch work for PDE solving using NVIDIA's Modulus. These include some assessments of how relevant physics-informed nets might be for studying cosmological systems, including self-gravitating matter and modifications to general relativity.
