Partial Differential Equations (PDEs)

Partial Differential Equations (PDEs)#

Solving partial differential equations (PDEs) using SciML/MethodOfLines.jl, a finite difference method (FDM).

Using neural networks to solve differential equations#

DiffEqFlux is generally more efficient than NeuralPDE because NeuralPDE also tries to discover physical rules in the data, which is mentioned in this thread.
