Functions
template<typename DispSpace , typename DensitySpace >
auto	smith::createKineticEnergyIntegrator (smith::Domain &domain, const mfem::ParFiniteElementSpace &velocity_space, const mfem::ParFiniteElementSpace &density_space)
	Utility function to construct a smith::functional which evaluates the total kinetic energy.
template<typename DispSpace , typename DensitySpace >
gretl::State< double >	smith::computeKineticEnergy (const std::shared_ptr< smith::Functional< double(DispSpace, DispSpace, DensitySpace)>> &energy_func, smith::FieldState disp, smith::FieldState velo, smith::FieldState density, double scaling)
	Utility function which computes the kinetic energy and returns it as a gretl state (with its vjp defined)
auto	smith::checkGradients (const gretl::State< double > &objectiveState, FieldState &inputState, FiniteElementDual &inputDual, double objectiveBase, gretl::DataStore &dataStore, double eps)
	testing utility to confirm order of convergence of the finite differences relative to the backprop gradient
auto	smith::checkGradients (const gretl::State< double > &objectiveState, gretl::State< double, double > &inputState, double &inputDual, double objectiveBase, gretl::DataStore &dataStore, double eps)
	testing utility to confirm order of convergence of the finite differences relative to the backprop gradient
double	smith::checkGradWrt (const gretl::State< double > &objective, smith::FieldState &input, double eps, size_t num_fd_steps=4, bool printmore=false)
	Testing utility function which runs a gretl graph num_fd_steps (with increasingly smaller finite difference steps) to check if the computed graph gradients are converging to the finite differenced gradients at the expected rate.
double	smith::checkGradWrt (const gretl::State< double > &objective, gretl::State< double, double > &input, double eps, size_t num_fd_steps=4, bool printmore=false)
	Testing utility function which runs a gretl graph num_fd_steps (with increasingly smaller finite difference steps) to check if the computed graph gradients are converging to the finite differenced gradients at the expected rate.
