To minimise the input effort, most of the required data is automatically reassigned during the Model checking… process. In this process, the data for lower layers (unless otherwise specified) is automatically assigned with the values of the layer above.

The preallocation covers the following data types:

• Initial potential heads (EICH)

• Hydraulic conductivity (KWER, KWEV, KFVH)

• Conductivity limits for calibration (KMIN, KMAX)

• Dispersivities (DISP)

• Porosities (PORO)

• Storage coefficients (SPEI, KSPE)

• Initial concentrations (AKON)

• Anisotropy of K-values (Z-KA)

• Compressibility of the overall system (KOMP)

If, for example, the initial potential heads for the 1st and 3rd node layer are in the mesh files for a 3D model with 6 node layers, the 2nd layer receives the values of the first and the 4th, 5th and 6th layers receive the values of the third layer.

If no vertical K-values are specified and no ratio to the horizontal K-values is defined (KFVH), the ratio is set to the value 0.1, i.e. KWEV = 0.1* KWER....
