Basic sub-grid obstacle drag model.
Details supplied by J Puttock 2/7/06.
Sub-grid drag term
<b> Sub-grid drag term <\b>
The resistance term (force per unit of volume) is given by:
\f[
R = -\frac{1}{2} \rho \vert \dwea{\vec{U}} \vert \dwea{\vec{U}}.D
\f[
R = -\frac{1}{2} \rho \vert \dwea{\vec{U}} \vert \dwea{\vec{U}}.D
\f]
where:
\f$ D \f$ is the tensor field "CR" in \f$ m^{-1} \f$

This is term is treated implicitly in UEqn.H
