The following list provides a summary of the major features of CVLGrid. It is recognized that there are other capabilities and improvements that can be made to CVLGrid 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_DSI, EFDC_SGZ, EFDC_EPA, and EFDC_Hydro

  • Import existing EFDC Model Grids and export CVL 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 (CVL) grids

  • Generate CVL 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
