NEW version of HGS (March 2022 - Revision 2372)
We’re pleased to announce the release of HydroGeoSphere Revision 2372 (March 2022).
In this release we are introducing several changes that should help HydroGeoSphere users to run better/more accurate simulations!
One major update is the inclusion of mesh quality metrics when you compile your model input files. Grok.exe now computes mesh quality metrics including element area, aspect ratio, edge ratio, min angle, max angle, and nearness to right triangle (triangles only) for each element in the 2D mesh. For each metric the mean, standard deviation, minimum/maximum values, and percentiles are calculated, and an ideal ‘target’ value is listed where appropriate (see image below).
We’ve also improved the implementation of Peclet and Courant number checks in HydroGeoSphere. HGS will now perform a check against specified Peclet and Courant numbers at all timesteps, and will issue a warning to the *.LST file when an exceedance is detected. These updates are supported by the following new commands:
The ‘peclet verbose’ command controls the level of output for Peclet warnings.
The ‘courant verbose’ command controls the level of output for Courant warnings.
The ‘report mesh quality’ command writes mesh quality metrics for the entire mesh to a Tecplot formatted ASCII file.
We’re also introducing a new command (‘channels to tecplot’) to help users visualize 1D channels. This command causes grok.exe to write the channel mesh including zone number and 3D node number to a Tecplot ASCII file.
Example of the “Mesh Quality Stats” written to the *.ECO file.
As always we are committed to resolving user-reported bugs and continued improvement to the user experience. Do you have suggestions for new commands or improvements to the user experience? Send your ideas to support@aquanty.com!
The latest installers are available on the HGS download page and a full list of changes/updates can be found in the release notes.
