Zoomy

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

Zoomy’s main objective is to provide a convenient modeling interface for complex free-surface flow models. Zoomy transitions from a symbolic modeling layer to numerical layer, compatible with a multitude of numerical solvers, e.g. Numpy, Jax, Firedrake, FenicsX, OpenFOAM and AMReX. Additionally, we work to support the PreCICE coupling framework in some numerical implementations, to allow for a convenient integration of our solver with your existing code.
