DSI has developed a new generation grid-building tool
...
called Grid+. This
...
tool replaces our long-running
...
CVLGrid. We have used the latest software platforms to create this new grid tool, which provides a more user-friendly GUI and a host
...
of enhanced features
...
. Grid+ makes the grid-building process faster and simpler for even the most challenging waterbodies. It features enhancements such as online background maps, improved orthogonalization routines, and the ability to download online bathymetry data.
Grid+ is fully integrated with EEMS, so it can be launched from EFDC+ Explorer GUI.
Several significant features of Grid+ are listed below.
Improved GUI
Object-oriented selection
Lat/Long coordinate system
Generate grid from splines
Integrated with EEMS
Shortcut keys use
Others
Summary of Capabilities
The following list provides a summary of the major features of Grid+. It is recognized that there are other capabilities and improvements that can be made to Grid+ to increase the ease of use and effectiveness of the software. It is anticipated that new features and improvements will be made as resources are available.
- Optimized for use with EFDC+, and EFDC
- Import existing EFDC Model Grids and export grids to EFDC Model format
- Load and edit an EFDC grid without changing the I,J mapping, thereby allowing boundary conditions to be maintained
- Display polygon data files in the workspace
- Define and edit polylines in the workspace
- Create, view, and edit layers
- Create and edit splines which are the basis for creating curvilinear grids
- Generate grids based on the defined splines
- Once a grid is generated, the user is able to:
- Improve orthogonality, globally or locally
- Refine or coarsen, globally or locally
- Regularize the cells
- Smooth the lines
- Reverse indices
- Adjust grid lines
- Add single cells to the grid
- Move cell nodes
- Delete cells
- Connect multiple grids
- The user can view
- Orthogonal deviation
- IJ coordinates
- Cell size (Dx, Dy)
- Vary cell colors
- Label corners
- Show N, S, E, W of cells
- Measure distances
- Load geo-referenced background images
- Change legends, labels and titles
- Export metafile data
