Normal tips flow direction

WebYou can define the flow direction at a mass flow inlet explicitly, or you can define the flow to be normal to the boundary. The procedure for defining the flow direction is as follows, referring to Figure 7.3.4: 1. Specify the flow direction by selecting Direction Vector, Normal to Boundary, or Outward Normals in the Direction Specification ... WebCells with undefined flow direction can be flagged as sinks using the Sink tool. If a cell has the same change in z-value in multiple directions and is not part of a sink, the flow direction is assigned with a lookup table defining the most likely direction. See Greenlee (1987).
