Partial differential equations (PDEs) play a central role in describing the dynamics of physical systems in research and in FiPy: A Finite Volume PDE Solver Using Python. In this paper we propose to solve PDE with a physical guided diffusion model whose reverse process is conditioned by initial/boundary and PDE guidance.
