Released On: 星期五, 12月 27, 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.

Prerequisites

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.

vc_redist.x64.exe

50	6月 10, 2020	Fixed typo in GIIC for "block solve relax table-ground-reaction" command Removed some decremented keywords in block solve relax so they do not show up in the inline help functions (ctrl ?). Added "overburden" keyword to "block insitu stress-topography". This is useful if your model does not extend to the actual ground surface.

46	5月 15, 2020	Added a keyword (edge_tolerance) to the "block zone gen manual" command. This keyword allows setting a tolerance that controls how close to a block edge a user specified gridpoint must be to be considered on the edge. This is intended to solve issues of numerical precision when generating zones from outside sources. The tolerance is specified as a fraction of the block corner-round-length. A typical value would be 0.1. It is unknown how large this value may be before the model results would be adversly affected.
45	4月 30, 2020	Fixed errors in block zone gen manual command. Changed block zone manua, command so that gridpoints are numbered in the order that they are defined. Previously they were numbered in reverse order which made the command more difficult to use.
