TensorDiffEq is a python package built on top of Tensorflow to provide scalable and efficient PINN solvers. TensorDiffEq’s primary purpose is for scalable solving of PINNs (inference) and inverse problems (discovery).

Additionally, TensorDiffEq is the only package that fully supports and implements Self-Adaptive PINN solvers and is the only Multi-GPU PINN solution suite that is fully open-source.

Many choices for your scientific machine learning solution exist, use TensorDiffEq if you require

A meshless PINN solver that can distribute over multiple workers (GPUs) for forward problems (inference) and inverse problems (discovery)
Scalable domains - Iterated solver construction allows for N-D spatio-temporal support
- support for N-D spatial domains with no time element is included
Self-Adaptive Collocation methods for forward and inverse PINNs
Intuitive user interface allowing for explicit definitions of variable domains, boundary conditions, initial conditions, and strong-form PDEs

What makes TensorDiffEq different?

Completely open-source
Self-Adaptive Solvers for forward and inverse problems, leading to increased accuracy of the solution and stability in training, resulting in less overall training time
Multi-GPU distributed training for large or fine-grain spatio-temporal domains
Built on top of Tensorflow 2.0 for increased support in new functionality exclusive to recent TF releases, such as XLA support, autograph for efficent graph-building, and grappler support for graph optimization* - with no chance of the source code being sunset in a further Tensorflow version release
Intuitive interface - defining domains, BCs, ICs, and strong-form PDEs in “plain english”
