Flux Discontinuity
This node represents a discontinuity in the mass flux across an interior boundary:
where the value
N
0
(SI unit: mol/(m
2
·s)) specifies the jump in total flux at the boundary. This can be used to model a boundary source, for example a surface reaction, adsorption or desorption.
Flux Discontinuity
In this section the jump in species flux (or surface source) is specified.
Select the Species check box for the species to specify and enter a value or expression for the material flux jump in the corresponding field. To use a different boundary condition for a specific species, click to clear the check box for the flux discontinuity of that species.
