Model objects & methods#
|
|
Collect all unique times from model packages and additional given times. |
|
|
Write Modflow6 simulation, including assigned groundwater flow and transport models. |
|
Discretization#
|
Discretization information for structered grids is specified using the file. |

Timing for all models of the simulation is controlled by the Temporal Discretization (TDIS) Package. |
Model settings#
|
The Output Control Option determines how and when heads are printed to the listing file and/or written to a separate binary output file. |
|
Iterative Model Solution. |
