Adds a Neumann contribution to the system of equations.
class fipy.boundaryConditions.fixedFlux.FixedFlux(faces, value)

Bases: BoundaryCondition

Adds a Neumann contribution to the system of equations.

Implements

\[\hat{n}\cdot\vec{J}|_\text{faces} = \text{value}\]

The contribution, given by value, is only added to entries corresponding to the specified faces, and is weighted by the face areas.

Parameters:

  • faces (FaceVariable of bool) – Mask of faces where this condition applies.

  • value (float) – Value to impose.

__repr__()

Return repr(self).
