Usage
Example of the model specification:
\verbatim
nucleateFluxModel
{
// Mandatory entries
type exponential;
// Optional entries
a <scalar>;
b <scalar>;
}
\endverbatim
where the entries mean:
\table

type | Type name: exponential | word | yes | -
a | Pre-factor coefficient | scalar | no | 6309
b | Exponent coefficient | scalar | no | 2.52
