# DirichletBoundaryCondition¶

class DirichletBoundaryCondition(value=None)

A Dirichlet type boundary condition.

Parameters: value (PhysicalQuantity of type energy | None) – The constraint value to fix the Hartree difference potential to. Default: The potential of the electrode for device calculations, 0.0 * eV otherwise.
