If you’ve been doing some 2D modeling, you most likely have run into what I call nuisance cell errors. You see them while your model is running and they can really slow down your simulation as the RAS chugs through iterations to try to come to a solution. The errors here are in the […]
***Update: I received a few very important comments about this post that I want to share. First, and this is very important: These methods are not meant to be used to do any kind of detailed bridge design or bridge scour analysis (contraction, abutment, or pier scour). The methods I present in this post are […]
The following article written by Mr. David Markwood of AECOM provides an excellent summary of the latest beta (candidate) version of HEC-RAS 5.0. Well worth the read! https://www.linkedin.com/pulse/hec-ras-50-beta-update-david-r-markwood-pe
*Update: Version 5.0.2 now does flow transects in RAS Mapper with profile lines. No longer necessary to use a 2D Area Connection to do this. A very common output request in 2D modeling is for flow over (through) a transect line. HEC-RAS 5.0 does not have a specific tool for extracting flow data along a […]
Continuing on with the discussion on leaking in 2D meshes, I want to highlight a new feature that will be included in the full release of Version 5.0 (hopefully due out early this summer). The new feature, 2D Area Breaklines, will make aligning cell faces on to high ground features a snap! Essentially, you draw […]
Many of us were hoping to see the official release of HEC-RAS version 5.0 around now (end of Feb, early March, 2015), but unfortunately there have been some delays due to a large amount of bug fixes and HEC won’t be releasing it as planned. I haven’t been provided with a new date, and I […]
