Outflow

This node provides a boundary condition at outlets where the vapor is transported out of the air domain. It is assumed that convection is the dominating transport mechanism across outflow boundaries, and therefore that diffusive transport can be ignored, that is:

This node can be applied on the exterior boundaries of a computational domain in which a Moist Air (Moisture Transport Interface) node or an Hygroscopic Porous Medium node is active.
