Number of outlets

geometry.n_outlets Step 02 · Geometry

The number of separate outlets in the model. It sets how many outlet patches (outlet_1, outlet_2, ...) the surface table offers; each must have at least one face.

Theory

An outlet is a patch on the outer skin where the flow leaves. Each outlet has its own pressure on the Boundary Conditions step (Outlet gauge pressure) and, with acoustics, its own acoustic termination; the results report the flow split between the outlets and the total pressure at each.

Several CAD faces of one tailpipe belong to the same outlet_N. The export rejects the assignment unless exactly this number of outlet patches have faces.
