Detailed Description

template<class BasicTurbulenceModel>
class Foam::laminarModels::Maxwell< BasicTurbulenceModel >

Maxwell model for viscoelasticity using the upper-convected time derivative of the stress tensor. See http://en.wikipedia.org/wiki/Upper-convected_Maxwell_model.

The model includes an additional viscosity (nu) from the transport model from which it is instantiated, which makes it equivalent to the Oldroyd-B model for the case of an incompressible transport model (where nu is non-zero). See https://en.wikipedia.org/wiki/Oldroyd-B_model
