NeuralPDE.jl and PINA
NeuralPDE.jl is a comprehensive Julia-native PINN framework integrated into the SciML ecosystem, while PINA is a Python-based alternative offering similar core functionality, making them direct competitors for solving differential equations with physics-informed neural networks across different language preferences.
About NeuralPDE.jl
SciML/NeuralPDE.jl
Physics-Informed Neural Networks (PINN) Solvers of (Partial) Differential Equations for Scientific Machine Learning (SciML) accelerated simulation
Leverages symbolic PDE definitions via ModelingToolkit to automatically construct physics-informed loss functions, eliminating manual differentiation and constraint specification. Supports diverse equation types (ODEs, SDEs, RODEs, integro-differential equations) with advanced training techniques including quadrature strategies and adaptive weighting, while maintaining interoperability with Flux.jl, Lux.jl, and NeuralOperators.jl for flexible neural architecture selection and GPU acceleration.
About PINA
mathLab/PINA
Physics-Informed Neural networks for Advanced modeling
Builds on PyTorch, PyTorch Lightning, and PyTorch Geometric to provide modular Problem, Model, Solver, and Trainer APIs for both supervised learning and physics-informed tasks. Supports Neural Operators and graph-based architectures, with automatic differentiation for constraint enforcement (e.g., differential equations, boundary conditions) and multi-device training via PyTorch Lightning's distributed backend.
