January 19th Web Meeting:

How to Generate An Accurate and Efficient Mesh

Hydraulic modelers, 

Happy New Year!  We have a lot planned for the 2D Hydraulic Modeling User's Forum in 2023 and we will kick it off with our first meeting of the year on Thursday January 19th, 11:00-12:30 Mountain Time. The Zoom meeting link info is provided below. 

We will present best practices and tools for generating a mesh that accurately represents the terrain and hydraulic controls while still resulting in the most efficient simulation times. It is important to compare a mesh with the original terrain in order to assess how well it represents the terrain and whether or not key hydraulic controls are adequately captured.   The use of breaklines to represent hydraulic controls and variable mesh resolution will be discussed, including an overview of tools that are available in the SMS package to evaluate the accuracy of a mesh. 

If you have any questions on mesh development that you would like to see included in the presentation, please send them to Scott (scott.hogan@gmail.com).

If you missed the previous web meeting in November 2022, links to the web recording and follow-up demo are provided near the end of this email.
