SMARTFIRE INTERACTIVE MESHING SYSTEM

The SMARTFIRE Interactive Meshing System has the responsibility for creating a mesh of control volumes for the current scenario. The Meshing System has a dual mode of operation so that novice users can benefit from meshing expertise that is used to automatically create an appropriate mesh, but expert users also have the option of manually specifying a mesh or fine tuning an automatically generated mesh. The meshing system gives the user ultimate control in the choice of meshing decisions. The meshing system is fully aware of the impact of vents on the outside of a region and will accommodate such vents with the automatic creation of extended regions so that accurate vent flows are possible. The single most important aspect of a CFD simulation is the quality of the mesh and SMARTFIRE provides many mesh quality enhancing facilities which the user can opt to include or exclude for a particular mesh generation. When the user finally chooses to accept a mesh then the appropriate command script file and geometry file are generated so that the scenario can be run in the SMARTFIRE CFD Engine.

SMARTFIRE uses integrated Knowledge Based System (KBS) techniques to assist with the task of meshing a scenario. First the user specified geometry is analysed to try to match what nature of system is being created. Accurate recognition assists with the selection of the most appropriate meshing rules which will, in turn, help to produce an appropriate meshing solution. The meshing itself is controlled by a number of production rules which dictate how specific geometry features should be handled by the meshing system.
