4.5.3.13.1 Scalar Coefficients for Segment Models:

The result of the scalar coefficient models ${\alpha}$, ${\gamma}$, $a$, $b$, and $d$ is represented by the Interface Parameter Coeff (Table 4.20). The derivatives are contained in Parameters following the naming convention: The name starts with the prefix dCoeff. Since the characters '/' and '|' are reserved for MDL operators, the symbolic fraction is represented by the character ' '. The rest of the Parameter name is composed by the string ``d_'' and the MDL name of the according quantity.

Table 4.20: Parameters common to scalar segment coefficient Models

Name	Type	Description

dCoeff d_Cown	double	derivative of the Coefficient to the column quantity
dCoeff d_psi	double	derivative of the resulting coefficient to the electrostatic potential $\psi$
dCoeff d_MdlQuantity	double	derivative of the resulting coefficient to the value of the quantity MdlQuantity
