For a fast and effective data input for 3D models, the model checking automatically assigns the majority of the necessary data. Each layer receives the existing data from the layer above.

The following data types are assigned automatically:

Initial potential heads (EICH)

Permeabilities (KWER, KWEV, KFVH)

Limitation of the permeabilities (KMIN, KMAX)

Dispersivities (DISP)

Porosities (PORO)

Storage coefficients (SPEI, KSPE)

Initial concentrations (AKON)

Anisotropic conductivities (Z-KA)

Compressibility of the entire system (KOMP)

 

For instance, the input file for a 3D model with 6 node layers contains initial potential head for the first and third layers. Therefore, it follows that the second layer gets the values of the first one, while the fourth, fifth and sixth layers get the values from the third one.

If there are no vertical permeabilities or rather no ratio between the horizontal and vertical values specified (KFVH), the ratio is set to the default value 0.1, that means KWEV = 0.1*KWER.
