Predefined are the following units:

Length in [m]

Areas in [m²]

Volumes in [m³]

Angles in degrees [°]

 

The other data are defined as follows:

Permeability coefficients in [m/s]

Concentrations:

In a mass transport calculation using a tracer or a density-independent flow it is possible to enter the concentration with an "arbitrary" unit (i.e. [g/l], [[g/g], [mg/l], [kg/kg], etc.).

In a density-dependent mass transport calculation the concentration has to have the unit [kg (solute)/kg (solution)].

In a calculation with adsorption the concentration has to have the unit [kg/m³].

Temperatures in [°C]

Density in [kg/m³]

Material data (MATE) in [cm/s]

Transmissivities (TRAN) in [cm²/s]

 

The relevant time unit for in- and outflow is determined in the model file. Therefore, all in- and outflows of the model have to be converted to this time unit. The following time units are available: SECOND, DAY, MONTH, YEAR.

Mass inflow and outflow (QKON) are defined per time unit second.
