HEC-RAS Version 5.0.7 is now available!

Fellow RAS Users:  Please take note that a new version of HEC-RAS, Version 5.0.7, is now available to download.  This is purely a bug fix release, so there are no new (advertised) features.  You may download the new version here:

http://www.hec.usace.army.mil/software/hec-ras/

Please read the following announcement from Gary Brunner and the list of bug fixes described below.

  

             "We have released a new version of HEC-RAS called version 5.0.7 today.  This version is a bug fix only version (i.e. No new features).  Unfortunately there were some bugs in version 5.0.6 that were significant enough to warrant a new release of the software.  Enclosed are the HEC-RAS 5.0.7 release notes describing the bugs that were fixed.

                We are sorry for any inconvenience this may have caused you while using HEC-RAS.  We hope you enjoy the new version of the software.  As always, please keep us informed on any bugs you find, or your ideas for new features.  Here is the link to the HEC-RAS 5.0.7 download area of our webpage:

Warning:  A few new software checks have been added for Lateral Structures and SA/2D Hydraulic Connections.  When you run version 5.0.7 of HEC-RAS these data checks may stop your data set from running, until you address the issues listed in the error messages."

The following is a list of bugs that were found in HEC-RAS Version 5.0.6 and fixed for Version 5.0.7:

Bug Report for HEC-RAS 5.0.6

RAS Users:  Please give this "Known Issues" report a read if you're using Version 5.0.6.  If you've been doing a lot of 2D modeling, it's likely you have been affected by some of these.

This link includes a document of "Known Issues" found in version 5.0.6 of HEC-RAS to date.  The

document outlines all of the Issues (bugs) we have found so far.

                http://www.hec.usace.army.mil/software/hec-ras/known_issues.aspx

Please look closely at this document, as there as a few issues that are potential computational problems.  Specifically issues 1, 2, 5, and 7.  Please review these issues closely.  If you have any of these situations use the suggested work around, or solution to get past the issue.  Everyone should look at issue 1 and 2, as they are possible in many models.

Sorry for any inconvenience this may cause you.  Keep letting us know if you find other problems with the software.

HEC-RAS Version 5.0 Comments, Suggestions, and Bug Reports

Hi HEC-RAS users.  HEC is extremely busy dealing with bugs and questions at the moment.  They’re currently working mostly to fulfill their obligations for technical support to the Corps of Engineers only.  If you are trying out the new version 5.0 beta, and you discover a bug, or if you simply have a comment or suggestion, please post them to The RAS Solution Forum.  I’ve agreed to collect, filter, and screen bug reports and comments and periodically send to HEC.  You can get to the forum and two new sub-forums: “HEC-RAS Version 5.0 Bugs”, and “HEC-RAS Version 5.0 Suggestions/Comments”, by following this link or by clinking the “The RAS Solution Forum” button up above. 
http://hecrasmodel.blogspot.com/p/hec-ras-bloggery-forum.html

Please post in the appropriate folder and keep the comments civil and constructive.  If you have a bug report, please post in the “bugs” folder and include as much information as is practical, but still keep it as brief as possible.  If you discover a “work-around” in the meantime, please included that as well. 

Also, don’t forget to get the latest version of HEC-RAS 5.0 beta here:

HEC-RAS Version 5.0 beta Issue with HDF5 Viewer

Written by Christopher Goodell, P.E., D.WRE  |  WEST Consultants

A few testers have discovered a dll conflict when trying to open the new 5.0 beta version of HEC-RAS.  The following message appears:

This happens if you’ve installed the HDF5 Viewer as described in the new “Combined 1D and 2D Modeling with HEC-RAS” document on page 115. 

HDF5 is a new file format used by HEC-RAS to store 2D output as well as some 1D output (in addition to the standard output files and dss files).  The HDF5 file contains more output information than is currently available in the HEC-RAS graphics and tables, such as velocity information for cell faces and face points.  The HDF5 Viewer is currently the only way for users to access the 2D velocity output. 

The issue is resolved by uninstalling the HDF5 Viewer.  HEC will be posting an updated install soon that corrects this problem.
