Solver: laplacianFoam Description
laplacianFoam is a basic solver that simulates diffusion-driven scalar transport in both transient and steady-state forms. Primarily used for heat conduction, it efficiently incorporates volumetric heat sources in its computations.
While adept at managing homogeneous fluid properties and thermal diffusion equations, the solver does not extend to non-homogeneous fluid properties, turbulence, multiphase flows, or reactive flows. Its core application lies in modeling heat conduction in solids, guided by the Laplace and heat diffusion equations.
