UDEC 7.00 Update

Download Recent Update

Latest Version: 7.00.96 (Description)
Released On: Dienstag, Juli 2, 2024

Update Instructions

Getting Started with UDEC 7:

  • All commands in UDEC have changed! This is to provide future consistency and compatibility across all Itasca software. While some old commands may still work, this is not guaranteed.
  • There are sections in the program menu Help->help that list on to one mappings of the old to new commands.
  • There is an automatic command conversion tool built into the GUI version (not GIIC) of the program. Load the file (data, FISH, or GIIC project files) into the built-in editor and then click edit -> command conversion.
  • The new UDEC is built around the use of project files. These project files are different from the GIIC project files and have a different file extension. It is highly recommend to use project files as they provide a base for the location of the project and will store plot settings.
  • UDEC 7.00 is built on Visual Studio 2017. DLL’s from VS 2010 will not be compatible. There is not currently a template for creating UDMs in 2017. The header files and libraries required for this are included. The example solution that is included in the install may be modified for a new DLL. Instructions for doing this are in the Constitutive Model Volume of the PDF manual.
  • The help has been converted to provide guidance for the new commands. The keyboard shortcuts CTRL+space and F1 will list keywords in the editor.
  • The manual PDF files contain detailed background theory and instructions on how to use UDEC. The Command and FISH references have been moved to the online Help->Help.


Visual C++ 2017 Runtime Library

UDEC 7.0 requires the Microsoft Visual C++ 2017 Runtime Library. If these files have not been previously installed or are experiencing errors related to missing DLLs, the runtime may not be present and will need to be installed.

With administrative privileges run C:\Program Files\Itasca\UDEC700\exe64\vc_redist.x64.exe to install the necessary files. Note this step need only be performed once.
