Detailed Description

Function base class for exact solutions/initial conditions/boundary conditions. This is needed so that we can have solutions that depend on problem parameters with resorting to global variables.

◆ derivative()

virtual Vector<double> oomph::SolutionFunctorBase::derivative	(	const double &	t,
		const Vector< double > &	x,
		const Vector< double > &	u
	)		const

pure virtual

Call the derivative function.

Implemented in oomph::SolutionFunctor, oomph::deriv_functions::OrderReductionTest, oomph::deriv_functions::SimpleStiffTest, and oomph::deriv_functions::DampedOscillation.

Referenced by oomph::ODEElement::derivative_function().

◆ have_jacobian()

virtual bool oomph::SolutionFunctorBase::have_jacobian ( ) const

inlinevirtual

Is a jacobian function implemented?

     {
       return false;
     }

Referenced by oomph::IMRODEElement::fill_in_contribution_to_jacobian(), and oomph::ODEElement::fill_in_contribution_to_jacobian().

◆ initialise_from_problem()

virtual void oomph::SolutionFunctorBase::initialise_from_problem ( const Problem * problem_pt )

inlinevirtual

Overload to grab data from the problem.

◆ jacobian()

virtual void oomph::SolutionFunctorBase::jacobian	(	const double &	t,
		const Vector< double > &	x,
		const Vector< double > &	u,
		DenseMatrix< double > &	jacobian
	)		const

inlinevirtual

The derivatives of the derivative function with respect to u (note that this is not quite the jacobian of the residuals for an ODE problem defined by this solution: you also need the time derivative part there). Broken virtual function because not often needed.
