Zoomy#

Zoomy is a flexible modeling and simulation software for free-surface flows.

A model is written once as a symbolic PDE (Model -> SystemModel -> NumericalSystemModel). The solvers are templates written once as sympy graphs and printed for each backend: JAX (CPU, GPU, MPI, automatic differentiation), OpenFOAM and AMReX (C++, MPI, AMReX on GPUs), with preCICE coupling. A cross-backend test matrix checks that every backend passes the same tests.

Start with the quick start, the user guide or the test results.
