Notice: Support for Python 3.6 will be dropped in v.0.2.1, please plan accordingly!
Collocation-based PINN PDE solvers for prediction and discovery methods on top of Tensorflow 2.X for multi-worker distributed computing.
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”
