HEC-RAS 5.0.5 has been released!


HEC has released a new version of HEC-RAS called version 5.0.5 today.  This version is a bug fix only version (i.e. No new features).  Unfortunately in version 5.0.4 there was a bug in which User defined Manning's n value override regions for 2D Flow Areas (called "2D Area Manning's n Regions"), define in the Geometry editor, were not being applied to the 2D Faces.  So user's would be unaware that they were not getting modified Manning's n values for these override regions.  As this is a bad computational error, anyone that was using Manning's n override regions defined in the Geometry editor, should rerun their models with this new release of HEC-RAS 5.0.5.  

In addition to that bug, several other minor bugs were also fixed.  Please review the Version 5.0.5 Release Notes to see all of the bugs that were fixed for this release.
