Gradient Calculators

GradientCalculator is the user-facing dispatcher that PhysicsInformer uses internally based on the grad_method argument. The individual per-method Gradients* modules are exposed for advanced users that need to compute spatial derivatives outside of the PhysicsInformer pipeline.
