Flow Continuity
The
Flow Continuity
condition is suitable for pairs where the boundaries match; it prescribes that the flow field is continuous across the pair.
The parts of the boundary where a source boundary lacks a corresponding destination boundary and vice versa will get conditions from other boundary conditions under the physics interface acting as fallback boundary conditions on the nonoverlapping parts. By default, the
Wall
node is used as fallback unless another feature has been selected for the boundary.
