Simulation Time Unit: Each time when the time unit in the Simulation Time Unit group is changed, PMWIN Pro will update the period length in the table, if Auto Update Period Length is checked. Note that changing the time unit does not affect the user-specified parameter values. • Simulation Flow Type: PMWIN Pro allows to perform steady state or transient flow simulations by selecting an option from the Simulation Flow Type group. It is possible to run a steady state simulation over several stress periods.

Telescoping Flow Model (Fig. 12): This tab creates local-scale sub-models from a regional scale model. To create a sub-model, select an existing PMWIN Pro model and specify the sub-region. Then click the Convert button. Prior to converting, the flow simulation of existing PMWIN Pro model must be performed. The sub-region is defined by the starting and ending columns and rows. PMWIN Pro automatically transfers the model parameters and the calculated heads from the regional model to the sub-model.

7) and cell-by-cell conductance values of the river, drain, general-head boundary, and stream are scaled by the cell volume. For example, if a well cell is refined to four cells, all four refined cells will be treated as wells, each with 1/4 of the original pumping rate. The sum of their pumping rates remain the same as that of the previous single well. 2. The parameters of polylines, which are used to define river, drain, general-head boundary, or stream, remain the same, since they are grid-independent.
