Additional calculations and inputs are possible in the GEONEU module:

Initial values

(only in the 3D model, only if the GEONEU module is selected)

This determines which initial potential head values are used as the basis for calculating the relative K values

Computation method

The GEONEU module must be selected for a horizontal model with a three-dimensional sub-area because the SITRA module cannot calculate this type of model. The theory of the path line calculation is explained in the "How To" chapter.

Equation solver

If the GEONEU module is selected, only the iterative solution method or the direct equation solver are available. The different equation solvers and the cancellation criteria have already been described in the section "Advanced settings in the SITRA module" .
