  DEEPSOIL v3.7

  August 07, 2009

DEEPSOIL v3.7 is now available for download.  A number of updates have been made to the program since the release of v3.5, including:

• A DEEPSOIL v3.7 icon is now added to the user’s desktop for ease of access to the program
  
• Updated terminology for selecting analysis options
  
• Recommended and default values for a select set of analysis parameters
  
• A user-optional beta feature of exporting output data to a Microsoft Excel file* for both standard and batch mode analyses
  *This feature is currently time-consuming depending on the number of layers in the analysis, but will be updated with future releases
  
• Additional output such as the “Maximum Stress Profile” is now included in all exported output
  
• Minor interface-related errors have been fixed
  
• A new energy-based pore water pressure generation model is now available for nonlinear analyses: the GMP/UIUC model. Please see the DEEPSOIL Manual for further details.
  
• Improvements have been made to the functionality of the cell tables within DEEPSOIL. Some of these improvements include:
  
  Pressing the “DELETE” key will now clear the contents of the selected cell;
  
  The hotkeys Ctrl+A, Ctrl+C, Ctrl+X, and Ctrl+V will now perform the Select All, Copy, Cut, and Paste commands, respectively;
  
  When pasting data to a cell table, previous versions of DEEPSOIL would only paste data into the currently selected cells. This version functions similarly to pasting data into a Microsoft Excel spreadsheet, whereby only the initial destination cell needs to be selected;
  
  Double-clicking a cell containing layer data (Step 2) will immediately open the Layer Properties window. Please see the DEEPSOIL Manual for further details.
  
• All other updates from previous DEEPSOIL releases.  A text file listing all of the updates which have been made to DEEPSOIL since 2008 is available here.
