XP Software’s xpertcare program for xpstorm provides quarterly releases for current subscribers. Each year XP Software releases a major upgrade, which is then followed by 2-3 updates that are applicable to that year’s upgrade in the form of Service Packs.

Version 2011 has exciting enhancements for 1D users and 2D users. In addition to a full maintenance list (available here), users can expect to receive the following enhancements:

• All xpstorm users with the DTM add-on module receive 10,000 cells of the xp2D module. This truly makes xpstorm a fully integrated 1D/2D module for all users!

• New Multiple Domain option for xp2D users. This feature adds versatility and accuracy to overland flow modeling.

  Use smaller grid cells on complex terrain, open channels or urban areas. Economize with larger grid cells for less complicated terrain.

  Easily rotate grids to correspond with terrain details such as roadways or flow paths.

  Link the grids so that the calculations and visualizations flow seamlessly and accurately across the entire 2D area.

• Dual Drainage Batch Converter. This new tool converts single conduits to multilinks and adds a second open channel to represent street and overland flows. This automation replaces a time-consuming and error prone manual task to convert single conduits for dual drainage.

• Basin or Pond Optimization has been enhanced to allow a total of four automated design options. You assign maximum levels for downstream conduits, maximum HGL for the pond, a combination of the two, as well as these four options:

- Upsizing of downstream conduits to not exceed a desired maximum level in the storage.

- Resize the basin. If the basin’s maximum HGL is exceeded, the basin will be resized.

- Resize downstream pipes and basin.  The method first designs the basin using the existing downstream conduits. If a sufficient size is found, the flows on the downstream conduits are checked.  If a flow limit is exceeded, the pipe size is decreased and the method restarts with designing the basin.

- Limit downstream discharge.

• Time of Concentration Calculator: A calculator for Time of Concentration / Time to Peak has been added and linked to the Unit Hydrograph and SCS Hydrology runoff method dialogs. Nine calculation methods are available: Friend’s Equation, Modified Friend Formula, Kinematic Wave, Alameda, Izzard, Kerby, Kirpich, Federal Aviation Authority, and Bransby Williams.

• Users can now show velocity magnitude and direction with water elevation at Point Time Series Outputs for 2D models.  Any number of points can be digitized throughout the active areas in a 2D model to record elevation and velocity at that point.

• Enhanced external data exchange for both 1D and 2D:
  • The 2D Grid can be imported from GIS polygon files in the same manner as other layers allowing fast model creation from existing geometry.
  • The 2D vectors layer can export an ESRI grid file for mapping velocity and flow vectors.  The export allows the user to define grid cell size for this mapping.
  • While importing the geometry of links and nodes from GIS shape and MID/MIF files users can now assign attributes to XP database fields.  The objects can now be created and the data imported with a right-click on the node and link layers.
