Detailed Description

Neumann boundary condition (i.e., constant derivative)


The value passed must not be the value of the derivative. Instead, it must be comprehensive of the grid step between the first two points--i.e., it must be the difference between f[0] and f[1].

Member Function Documentation

void applyBeforeApplying (TridiagonalOperator &) const [virtual]

This method modifies an operator $ L $ before it is applied to an array $ u $ so that $ v = Lu $ will satisfy the given condition.

Implements BoundaryCondition< TridiagonalOperator >.

void setTime (Time t) [virtual]

This method sets the current time for time-dependent boundary conditions.

Implements BoundaryCondition< TridiagonalOperator >.
