PetIBM vs PySWMM
Both stand on physics simulation software. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan LinuxMacSelf-hosted
PetIBM provides specialized immersed-boundary flow solvers with CPU, GPU, distributed, and developer-oriented options. Its Linux focus and dependency requirements are central considerations for setup.
