Usage

Example of the model specification:

nucleateFluxModel
{
    // Mandatory entries
    type            exponential;

    // Optional entries
    a               <scalar>;
    b               <scalar>;
}

where the entries mean:

Property	Description	Type	Reqd	Deflt
type	Type name: exponential	word	yes	-
a	Pre-factor coefficient	scalar	no	6309
b	Exponent coefficient	scalar	no	2.52
