            For a transient calculation of groundwater flow, a stable initial
            condition is required. This initial condition is found by the
            program GGU-TRANSIENT from a file (e.g. PLGW.DA1) which is created
            from a previous analysis undertaken with the program
            GGU-SS             FLOW 2D
            . This data must be loaded as the first action after starting the
            program. In addition to the analysis results, the data file also
            contains the relevant soil and input parameters for the analysis.
            These fundamental parameters (e.g. k, neff etc.) cannot be modified
            in the GGU-TRANSIENT program. If they are altered, then the soil
            parameters will no longer match the potentials and flows, and the
            transient calculations will be meaningless.
            Of course, for all groundwater flow problems (planar vertical,
            planar horizontal and axisymmetric), it is necessary to input
            parameters which are appropriate for a transient flow calculation.
            In addition to soil parameters, time-dependent boundary conditions
            can be defined for the transient program. Time dependent boundary
            conditions (potential or flow) are entered as polynomial functions.
            These polynomial functions can be defined at single or multiple
            system nodes. These (transient) soil parameters and polynomials can
            be saved in a separate boundary data file, to be available for a
            subsequent calculation.

            Boundary conditions that were defined in the course of the GGU-SS
            FLOW 2D calculation, are automatically saved in the input data file
            (e.g. PLGW.DA1). These are assumed to be constant for the duration
            of the calculation in GGU-TRANSIENT, unless they are specifically
            cancelled in the program GGU-TRANSIENT. The program GGU-TRANSIENT
            allows one to view the initial static conditions (e.g. PLGW.DA1) on
            the screen to enable confirmation that the correct system is being
            solved.
            The GGU-TRANSIENT program is not able to display the transient
            results. The output program GGU-PLGW is available for this purpose.
