SMS:3D Cartesian Grid Module
| This article is for a model that is under development by Aquaveo and its partners.
The model is not available to the public at this time. It is not known when or if the model will be released.
The content may not apply to current or older versions.
This module is currently being developed for future interfaces.
The 3D Cartesian Grid Module allows the creation of 3D grids which can be used for surface-water modeling. Currently there are no models that use this module.
3D Grid Types
Two types of 3D grids are supported in SMS: cell centered and mesh centered. When computations are performed on a mesh-centered grid, the computation points are the grid nodes or the corners of the grid cells. With a cell-centered grid, computations are performed at the cell centers.
When a dataset is imported to a cell-centered grid, there is one value in the dataset for each cell. To use contouring or fringing the values at the cell corners must be known. Therefore, whenever contouring or fringing is performed, the values at the cell centers are interpolated to the cell corners. Interpolation to cell corners is only done for visualization. All computations performed using the Data Calculator are performed on the original values at the cell centers. With mesh-centered grids, all visualization and computations are performed at the cell corners and no interpolation is necessary.
All of the model interfaces in the 3D Grid module are based on cell-centered grids. Mesh-centered grids are useful for interpolation and isosurface visualization since no extra interpolation is necessary.
