Class Foam::XiGModel::basicSubGrid Description Basic sub-grid obstacle flame-wrinking generation rate coefficient model. Details supplied by J Puttock 2/7/06. \f$ G_{sub} \f$ denotes the generation coefficient and it is given by \f[ G_{sub} = k_{1} /frac{\vert \dwea{\vec{U}} \vert}{L_{obs}} \frac{/Xi_{{sub}_{eq}}-1}{/Xi_{sub}} \f] and the removal: \f[ - k_{1} /frac{\vert \dwea{\vec{U}} \vert}{L_{sub}} \frac{\Xi_{sub}-1}{\Xi_{sub}} \f] Finally, \f$ G_{sub} \f$ is added to generation rate \f$ G_{in} \f$ due to the turbulence.
