Attribute: QKON = [mass/node/second]/[W] (node-wise) (transport model only)

The QKON attribute can be used to assign a fixed mass flow (mass per second) at individual nodes without needing to define the corresponding fluid flow volume or a fixed heat production rate. The mass inflow/outflow must be specified with the time unit in seconds.

The heat production rate results from the amount of heat generated in 1 m³ of material in one second (e.g. through friction or radioactive decay). In SPRING, QKON is entered in the unit [W] for heat transport, which refers to 1 m³ of surrounding material (water and matrix). QKON can be defined as a transient boundary condition as well.
