Overview

EFM 6.0.026

Version 6.0 supersedes version 5.0, which was released in September 2020.  Installing version 6.0 will not overwrite any previous software versions.  Also, the new version is backward compatible, which means that any HEC-EFM project files created with previous versions are fine and ready for use with version 6.0.

Version 6.0 is available as both an install package (.exe) and an archive of files (.zip).  The install package guides the user through the install process and requires computer administrative rights for successful use.  Installing with the archive of files does not require administrative rights.  Simply extract all contents of the archive to the desired computer location and the software will be ready for use.

During numerical testing performed at HEC, version 6.0 exactly reproduced quantitative results generated with versions 5.0, 4.0, 3.0, and 2.0, but users are encouraged to verify their existing applications.

Version 6.0 is programmed in Visual Basic .NET.  It includes several new features, improved software behaviors, and bug fixes for issues that were not detected prior to release of version 5.0.  Language resources prepared for version 5.0 will need to be updated for use in version 6.0.  The Quick Start Guide has also been updated and is currently the most complete and comprehensive source of information about the software. 

There were 26 beta versions of EFM 6.0.  An estimated 55 bug fixes were completed for new features in version 6.0.

HEC-EFM Plotter is designed to help users view, navigate, and interpret output generated by HEC-EFM.  It is important to note that Plotter does not generate new output; Plotter only displays output from EFM.

Version 4.0 supersedes version 3.1, which was released in February 2021.  Version 4.0 is available as an install package (.exe) and as an archive of files (.zip).  Both are easy to use and have the same content.  The install package guides the user through the install process and requires computer administrative rights for successful use.  Please note that using the install package will replace any previously installed version located in the destination selected by the user during installation of EFM Plotter.  Installing with the archive of files does not require administrative rights.  Simply extract all contents of the archive to the desired computer location for EFM Plotter.  The software will be ready for use after extraction.

Version 4.0 is backward compatible, which means that any project files created with previous versions of Plotter are fine and ready for use.

Version 4.0 includes improved software behaviors and bug fixes for issues that were not detected prior to release of version 3.1.  Language resources prepared for version 3.1 will need to be updated for use in version 4.0.  The EFM Quick Start Guide remains the most complete and comprehensive source of information about Plotter.

There were 44 beta versions of EFM Plotter 4.0.  An estimated 31 bug fixes were completed for new features in version 4.0.
