The coefficients
and
in (4.7) -
(4.8) are computed with Models derived from the classes
CoeffModel_beta and CoeffModel_phi respectively.
Quantity values determined by Dirichlet type boundary conditions
(4.9) - (4.10) are computed by Models
derived form the base class DirichletModel.
The naming conventions of their Interface Parameters are
similar to the according conventions for segment models described in
Section 4.5.3.13. Different is that each quantity is
represented by two values assigned to the two material segments forming the
boundary. In this context the material segment indexed with '1' represents
the segment in the first array index of the boundaryModel
Parameter of the PromisNTSetupModel instance
(Section 4.5.3.5).
