Member Function Documentation

void BodyRHS

(

const Vect< double > &

f

)

Add Right Hand Side Contribution.

Parameters:

[in]

f

Vector containing the source given function at mesh nodes

void BoundaryRHS	(	int	n,
		double	p
	)

Add Neumann contribution to Right-Hand Side.

Parameters:

[in]	n	Parameter to select equal to 0 if the condition is at the left end of the domain and different if it is at the right of it
[in]	p	Value of flux to add

Note:

This member function is to be invoked only for the first or last element
