Some momentumTransportModels like the laminar Stokes and generalisedNewtonian models do no solve transport equations and the transport coefficients they provide can be predicted at the beginning of the time-step rather than corrected at the end, after conservative fluxes are available. A particular advantage of this approach is that complex data cached in the momentumTransportModels can now be deleted following mesh topology changes and recreated in the predict() call which is more efficient than attempting to register and map the data. Currently the predict() function is only used for the Stokes and generalisedNewtonian models but it will be extended in the future to cover many LES models which also do not require the solution of transport equations. All solvers and solver modules have been update to call the momentumTransportModel::predict() function at the beginning of the time-step, controlled by the new PIMPLE transportPredictionFirst control as appropriate.
