Background

This article documents compatibility of each OpenRoads/OpenSite/OpenRail Designer product and OpenFlows storm-sewer product and information about respective versions supported.

Starting with OpenRoads Designer version 10.08.00.88, the term "SUBSURFACE UTILITIES AND DESIGN ANALYSIS" has been officially changed to "DRAINAGE AND UTILITIES" though the functionalities are same.

A Note on System and Hardware Requirements

For hardware requirements (RAM, CPU, Video card), refer to the Readme.PDF file included in the installation folder of your respective Bentley product. In general, hardware requirements are highly dependent on the size and complexity of the model. The more elements and more complexity in the model and the longer the simulation duration, the more memory it will take up and the more a faster CPU will impact overall performance.

Note on Compatibility

Each version of OpenRoads/OpenSite/OpenRail Designer uses a different version of the OpenFlows technology products (SewerGEMS / StormCAD / SewerCAD / CivilStorm). The exact OpenFlows version does not always match up with the released version of the OpenFlows applications, but the below table shows the general compatibility.
As with the OpenFlows products, projects saved in a latest version generally cannot be opened by an earlier older version (with respect to the "compatible OpenFlows storm/sewer version" noted below). There are exceptions though, for example models saved in 2023 and 2024 can still be opened in 10.04.00.XX. See: Model backward / forward compatibility
To open an OpenRoads/OpenSite/OpenRail Designer project in e.g. SewerGEMS, select "DGN" in the Files or Type dropdown in the File Open dialog of SewerGEMS.
