Abstract

A novel automatic grid generation method for complexCFD applications has been developed, driven by theneed of the industrial CFD practitioner to reducethe turnaround time from an initial CAD geometry toobtaining a flow simulation. The method uses asubdivision strategy, allowing hanging nodes in aCartesian unstructured mesh environment and iscombined with a non-overlapping, semi-structuredsurface grid. Unusually, the surface grid is the endrather than the starting point of the presentapproach. This reversal of gridding strategy allowsusability to be enhanced, in that the gridgeneration is reduced to one automatic step. Thecapabilities of the method are demonstrated byreference to selected inviscid and viscous flowsolutions using the Fluent code Rampant v4.0 as aflow solver.
