4.5.3.14 Coefficients for Boundary Models

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).
