PhysicsNeMo

PhysicsNeMo is NVIDIA's open-source physics-ML framework (v2.x in 2026, Apache-2.0) offering complete training from data-driven to physics-constrained (PINN / soft & hard constraints), with preset physics equations and distributed training. Its Apache-2.0 license is very friendly to closed-source commercial use, making it the mainstream framework for industrial physics AI.

Use cases: Training industrial surrogates; embedding physics-constrained networks; large-scale training with HPC / GPU clusters.
