Abstract
A hybrid computational fluid dynamics (CFD) approach is provided for modeling a bounded domain by processing the domain to automatically locate a viscous region(s) by: dividing the domain into cells and determining flow characteristic values for cells; defining characteristic cutoff values using multiple cutoff percentiles of cells and the flow characteristic values, and defining ranges between cutoff values, and respective χ values, where one χ value is a highest χ value R; assigning χ values to cells based on the determined flow characteristic values in comparison to the cutoffs; selectively increasing the assigned χ value of a cell(s) sharing a border with a seed cell having χ value R; identifying a viscous region where multiple contiguous cells have assigned χ values equal or above a threshold; evaluating the viscous region(s) by performing viscous domain solve; and providing a model of the domain using results of the viscous domain solve.
