Any number of grids of varying sizes and/or orientations may be used in TUFLOW. Using multiple 2D domains requires that multiple 2D domains are licensed in TUFLOW.
To setup multiple 2D domains in SMS:
- Create multiple TUFLOW grids and associated grid components.
- Define a 2D/2D Linkage coverage and attributes (see below).
- Add all the 2D domains being used and the 2D/2D Links Coverage to the simulation.
There are a few important items to keep in mind when setting up a 2D/2D Linkage coverage.
- You need a polygon enclosing each domain you wish to use. In the case below, you would need a polygon that covers the area outside of the main channel polygon.
- Each polygon needs to be linked to a specific 2D domain. This is done by double clicking on each polygon and specifying the appropriate 2D grid.
- Set the vertex spacing on the arcs that join multiple 2D domains. The spacing along these arcs determines how flows move between the domains. The rule of thumb to start with is to have the vertex spacing equal to 1.5 times the larger cell size.
