FARGOpy is a Python package designed for the analysis and visualization of hydrodynamical simulations produced by the FARGO3D code. It provides a reproducible and physically consistent analysis pipeline for refined spherical grids, where curvilinear geometry and spatial non-uniformity often hinder the use of generic tools. The package supports the manipulation of scalar and vector fields, offering tools for multidimensional interpolation, flux calculation through arbitrary surfaces, and kinematic analysis in planetocentric frames. It is particularly robust for post-processing planet-disk interaction simulations and studying circumplanetary environments.
