The attributes 1KON, KONZ and QKON can be specified in the transient input file. The unit is: [concentration unit of the model/node]. If the concentration in the model file is e.g. in [kg/kg], the concentration in the transient input file must be specified in the same unit. For the heat transport calculation, the unit is [°Celsius].

Fixed concentrations:

Attribute: 1KON [see above] (node-wise)

The node values for fixed concentrations/temperatures can be changed. It is not (yet) possible to switch off fixed concentrations/temperatures boundary conditions (as with the fixed potential heads).

Inflow concentrations

Attribute: KONZ [see above] (node-wise)

The values for the concentrations/temperatures of inflow rates can be set or changed here for the first time. Inflow concentrations/temperatures can be 'switched off' by setting the concentration/temperature value to 0.

Mass inflow

Attribute: QKON, [mass/node/second] (node-wise)

The values for the mass inflow/outflow can be created or changed. The time unit is always seconds, regardless of the time unit defined under MENG. The mass inflow at a node can be 'switched off' by setting the QKON value to 0)

Heat production rate

Attribute: QKON, [W/node] (node-wise)

The values for the heat production rate can be created or changed. The unit [W] refers to 1 m³ of surrounding material (water and matrix), regardless of the time units defined in the transient input file. The heat production rate at a node can be 'switched off' by setting the QKON value to 0.
