What's new in SMS 12.3

The following is a list of the more significant changes and new features available in SMS 12.3.

Keep your license current by paying annual maintenance to continue receiving all available updates, releases, and technical support. New licenses include maintenance for 1 full year.

Hi-res Icons

High resolution displays caused icons and text in older versions of SMS to render very small. SMS now detects your display resolution and appropriately sizes icon bitmaps and fonts. Icons may also be sized manually
High Resolution Display with SMS 12.3

Virtual Earth Map Locator Updates

The online maps tools have been updated to be compatible with the latest publicly available image and map servers. The Virtual Earth Map Locator tool now utilizes Bing Maps, including road maps, aerial imagery, and bird's eye views for map navigation.

Generate an observation plot
from an arc

Right-clicking on an arc in an observation coverage now has the option to directly generate an observation plot from that arc.

Interactive Plot Data Points

It is now possible to interact with points on 2D plots and view point values.
Select Data Points

Default Contour Range Options

Preferences can be set for the default contour range of transient datasets. This is particularly useful for models such as SRH-2D where steady state conditions can be modeled, but output datasets are transient. It is often desirable to disregard dataset ranges for initial timesteps where the model is ramping up to the specified boundary conditions.

Polygon Transparency

A transparency can be set for filled polygons (such as materials) in the map Display Options.

New Module Tutorials

New tutorials are available for SMS including Grid Generation, Map Module, Mesh Generation, and Print Layout

SRH-2D Version 3.2 Now Supported

SMS 12.3 now supports the latest version of SRH-2D version 3.2.

New SRH-2D Tutorial

A new tutorial is available for SRH-2D that shows the process for making a summary table to compare the 2D hydraulic model results with 1D hydraulic model results.

Ability to create inflow-outflow link boundary conditions

A link can be used to simulate flow between two parts of a mesh that are not connected. When two arcs are selected in an SRH-2D Boundary Condition Coverage, one arc can be specified as the "Link Inflow" and the other arc as the "Link Outflow." The arcs can connect otherwise disconnected portions of a mesh.

Internal sink boundary condition options have been updated

Rating curves are now one of the available options for the sink flow type definition.

Link to HY-8 for culvert calculations via a table of flow rates—significantly reduces model computation time

Run times have been improved for SRH-2D models that include HY-8 culverts. At the beginning of the model run, HY-8 creates a table of flow rates that can be quickly referenced by SRH-2D, which reduces overall run time for the model.
