SMS:What's New in SMS 12.1

Release Notes

SMS 12.1 is scheduled for a Beta release in September 2015. The main functionality of this release is a new simulation based interface for the Coastal Modeling System (CMS). The interface to the CMS was removed in SMS 12.0 in anticipation of a new version of both interface and model and delays in the development cycle resulted in the intermediate version (12.0) that did not support this model.

This update of SMS includes several new capabilities and advancements which are outlined below.

General Features

Model Interfaces

• SMS includes a new simulation based interface for the Coastal Modeling System (CMS) (see - Fact Sheet and

- Product Description

• Polygons that share a common arc(s) can be merged into a single polygon.

Module Features

Mesh Module

• Mesh elements can be selected and converted into feature arcs. The arcs have the default attributes of the coverage they are assigned to.

Quadtree Module

• Cartesian grids (both regular and irregular) can be converted to Quadtrees by right clicking on the grid
• A Quadtree can be edited to conform to sizes specified on a polygon by polygon basis in a Quadtree Generation coverage by right clicking on the Quadtree and selecting the refine command.
• Quadtrees can be edited manually by selecting on or more cells, right clicking and selecting the Split Cell(s) or Merge Cell(s) commands.
  • The split command subdivides each selected cell into four cells.
  • The merge identifies the three sibling cells for each selected cell. If those cells have not been subdivided, the four cells are merged into a single cell. A cell at the base level cannot be merged.
• The elevation dataset on Quadtrees can be smoothed by right clicking on the Quadtree object and selection the Smooth... command.
• Datasets on a Quadtree can be interpolated to other geometric objects by right clicking on the Quadtree and selecting Interpolate to....
• A Quadtree is saved as a *.tel file when a CMS-Flow simulation is exported to native input files.

Model Features

SRH-2D

• New version of HY-8 allows reuse of culvert crossings in multiple simulations and projects.
