None of the current thermophysicalTransportModels solve transport equations in order to evaluate the thermophysical transport properties so it makes more sense that the evaluation occurs at the beginning of the time-step rather than at the end where conservative fluxes are available for transport solution. To enable this the correct() functions have been renamed predict() and called in the prePredictor() step of foamRun and foamMultiRun and at the beginning of the time-step in the legacy solvers. A particular advantage of this approach is that complex data cached in the thermophysicalTransportModels 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. An empty correct() function is included in addition to the new predict() function in thermophysicalTransportModel to support scalar flux transport closure in the future if needed. Additionally the two transport model corrector function calls in foamRun and foamMultiRun have been combined into a single postCorrector() call to allow greater flexibility in transport property prediction and correction in the modular solvers.
