Detailed Description

Base abstract class for time dependent operators: (x,t) -> f(x,t)

Definition at line 68 of file operator.hpp.

Constructor & Destructor Documentation

mfem::TimeDependentOperator::TimeDependentOperator	(	int	n = `0`,
		double	_t = `0.0`
	)

inlineexplicit

Construct a "square" time dependent Operator y = f(x,t), where x and y have the same dimension 'n'.

Definition at line 76 of file operator.hpp.

mfem::TimeDependentOperator::TimeDependentOperator	(	int	h,
		int	w,
		double	_t = `0.0`
	)

inline

Construct a time dependent Operator y = f(x,t), where x and y have dimensions 'w' and 'h', respectively.

virtual void mfem::TimeDependentOperator::ImplicitSolve	(	const double	dt,
		const Vector &	x,
		Vector &	k
	)

inlinevirtual

Solve the equation: k = f(x + dt*k, t), for the unknown k. This method allows for the abstract implementation of some time integration methods, including diagonal implicit Runge-Kutta (DIRK) methods and the backward Euler method in particular.
