- class fipy.boundaryConditions.nthOrderBoundaryCondition.NthOrderBoundaryCondition(faces, value, order)¶
Bases:
BoundaryConditionAdds an appropriate contribution to the system of equations
Implements
\[\hat{n}\cdot\nabla^\text{order} \phi |_\text{faces} = \text{value}\]This boundary condition is generally used in conjunction with a ImplicitDiffusionTerm that has multiple coefficients. It does not have any direct effect on the solution matrices, but its derivatives do.
Creates an NthOrderBoundaryCondition.
- Parameters:
faces (
FaceVariableofbool) – Mask of faces where this condition applies.value (
float) – Value to impose.order (
int) – Order of the boundary condition. An order of 0 corresponds to a FixedValue and an order of 1 corresponds to a FixedFlux. Even and odd orders behave like FixedValue and FixedFlux objects, respectively, but apply to higher order terms.
- __repr__()¶
Return repr(self).
