Select Engines

Print this Topic Previous page Return to chapter overview Next page

The Single Run workflow step is used to select the Flow and Transport Engines you wish to include in the model run. Visual MODFLOW Flex requires you to select a flow engine for a particular run.  Running a transport engine, ZONEBUDGET, and/or MODPATH is typically optional.

 

 

The flow and transport engine(s) available for selection are based on the flow and transport options chosen at the the Define Modeling Objectives workflow step as well as the selected grid type.  For example, parent/child grids used with MODFLOW-LGR flow models are not currently compatible with any of the transport engines, ZONEBUDGET, or MODPATH.  However, model results from an LGR run can be extracted to a standard finite difference subgrid and subsequently run with transport, ZONEBUDGET, and/or MODPATH.

 

The table below lists all supported engines and utilities supported in Visual MODFLOW Flex.  For more information on which flow and transport engines are compatible with the supported modeling objectives, see the respective sections on Flow and Transport modeling objectives.

 

Engines supported in the Numerical Workflow

Flow

Transport

Utilities

 

MODFLOW-2000

MODFLOW-2005

MODFLOW-LGR

MODFLOW-NWT

MODFLOW-SURFACT

SEAWAT

 

 

MT3DMS

RT3D

 

 

MODFLOW-SURFACT

SEAWAT

 

ZONEBUDGET and

MODPATH

 

 

NOTES:

MODFLOW-LGR should only be run when you have defined a child grid and ran Conceptual to Numerical Conversion from the Conceptual Modeling workflow.

 

MT3DMS and MODPATH are not supported by MODFLOW-LGR.  Visual MODFLOW Flex uses MODFLOW-LGR v.1.0

 

Transport Engines and MODPATH are not supported by MODFLOW-USG

 

MODFLOW-SURFACT and SEAWAT are coupled flow and transport models and are not supported with MT3DMS or RT3D.
