PhiFlow is an open-source Python simulation toolkit for solving partial differential equations with support for optimization and machine learning workflows. It integrates with NumPy, PyTorch, JAX, and TensorFlow to provide end-to-end differentiable physics simulations, such as fluid dynamics, combined with neural network models.

Use cases

• run differentiable fluid simulations for machine learning
• train neural networks with physics simulation in the loss loop
• solve PDEs with automatic differentiation
• build physics-based deep learning models
• simulate smoke and fluid dynamics in Python
• optimize simulation parameters via gradients

When to choose

• you need gradients flowing through physics simulations into ML models
• you want a PDE solver that works with PyTorch, JAX, or TensorFlow
• you are doing research in physics-based deep learning or differentiable simulation

When to avoid

• you need a general-purpose CFD tool with production-grade solver accuracy
• you only need non-differentiable simulation without ML integration
• you need simulation domains outside PDE-based physics like rigid body dynamics
