Web11 de abr. de 2024 · The interior boundary doesn't store a normal so the normal is created in Fluent - not all facets on the boundary necessarily point in the same direction. Hence the interior-wall-interior trick. If you want the net mass flow then either align the normals or use a Custom Field Function of the sum of velocity component*cell area*density WebUsage. The Flow Direction tool supports three flow modeling algorithm: D8, Multiple Flow Direction (MFD), and D-Infinity (DINF). The D8 flow method models flow direction from each cell to its steepest downslope neighbor. The output of the Flow Direction tool using the D8 flow direction type is an integer raster whose values range from 1 to 255.
