Most auxiliary variables will not be used by the GWF-GWF Exchange, but they will be available for use by other parts of the program. If an auxiliary variable with the name ``ANGLDEGX'' is found, then this information will be used as the angle (provided in degrees) between the connection face normal and the x axis, where a value of zero indicates that a normal vector points directly along the positive x axis. The connection face normal is a normal vector on the cell face shared between the cell in model 1 and the cell in model 2 pointing away from the model 1 cell. Additional information on ``ANGLDEGX'' is provided in the description of the DISU Package. If an auxiliary variable with the name ``CDIST'' is found, then this information will be used as the straight-line connection distance, including the vertical component, between the two cell centers. Both ANGLDEGX and CDIST are required if specific discharge is calculated for either of the groundwater models.

One value is read for every model cell. For simulations in which the first stress period is steady state, the values used for STRT generally do not affect the simulation (exceptions may occur if cells go dry and (or) rewet). The execution time, however, will be less if STRT includes hydraulic heads that are close to the steady-state solution. A head value lower than the cell bottom can be provided if a cell should start as dry.

description character string value that defines the the prioritization system for the diversion, such as when insufficient water is available to meet all diversion stipulations, and is used in conjunction with the value of FLOW value specified in the STRESS\_PERIOD\_DATA section. Available diversion options include: (1) CPRIOR = `FRACTION', then the amount of the diversion is computed as a fraction of the streamflow leaving reach IFNO ($Q_{DS}$); in this case, 0.0 $\le$ DIVFLOW $\le$ 1.0. (2) CPRIOR = `EXCESS', a diversion is made only if $Q_{DS}$ for reach IFNO exceeds the value of DIVFLOW. If this occurs, then the quantity of water diverted is the excess flow ($Q_{DS} -$ DIVFLOW) and $Q_{DS}$ from reach IFNO is set equal to DIVFLOW. This represents a flood-control type of diversion, as described by Danskin and Hanson (2002). (3) CPRIOR = `THRESHOLD', then if $Q_{DS}$ in reach IFNO is less than the specified diversion flow DIVFLOW, no water is diverted from reach IFNO. If $Q_{DS}$ in reach IFNO is greater than or equal to DIVFLOW, DIVFLOW is diverted and $Q_{DS}$ is set to the remainder ($Q_{DS} -$ DIVFLOW)). This approach assumes that once flow in the stream is sufficiently low, diversions from the stream cease, and is the `priority' algorithm that originally was programmed into the STR1 Package (Prudic, 1989). (4) CPRIOR = `UPTO' -- if $Q_{DS}$ in reach IFNO is greater than or equal to the specified diversion flow DIVFLOW, $Q_{DS}$ is reduced by DIVFLOW. If $Q_{DS}$ in reach IFNO is less than DIVFLOW, DIVFLOW is set to $Q_{DS}$ and there will be no flow available for reaches connected to downstream end of reach IFNO.

The largest time step will be calculated such that the advective fractional cell distance (ATS\_PERCEL) is not exceeded for any active cell in the grid. This time-step constraint will be submitted to the ATS Package, perhaps with constraints submitted by other packages, in the calculation of the time step. ATS\_PERCEL must be greater than zero. If a value of zero is specified for ATS\_PERCEL the program will automatically reset it to an internal no data value to indicate that time steps should not be subject to this constraint.
