An exciting new development in FLOW-3D HYDRO 2024R1 is the introduction of a Site coordinate system (sometimes called a local or project coordinate system) that facilitates working with geographic coordinate systems by allowing objects such as topography and bathymetry to be defined in a geographic coordinate system (e.g., UTM) while other objects are defined in a convenient local coordinate system (e.g., BIM coordinates). This new capability reduces the time, effort, and risk associated with manual coordinate transformations during the model setup with a clear, simple interface for setting the Site coordinate system, as well as an option to simply read it from a Revit shared coordinate file.
A second development for FLOW-3D HYDRO is to include LandXML and the triangulated raster surfaces into the EXODUS II-based output files. This makes the full topography/bathymetry available when postprocessing, making it easier to convey results to your audience in a way that focuses on the story rather than the modeling details.
