How do the above OpenFlows product licenses work with element limits? (feature levels) For example number of pipes, links, inlets, ponds, etc.

How do the license feature levels work between storm and sewer products? For example if I own a license for SewerGEMS how many inlets do I get in my license if I used the GVF-Rational(StormCAD) solver in SewerGEMS?


Bentley's OpenFlows products are licensed by "feature level", which is a combination of the maximum number of elements that can be present in a model, and the allowed platforms (that the program can integrate with.) The feature level is handled by your license and is independent from the product installation. There is only a single installation file for the product, and the number of pipes/inlets/ponds that it uses and records usage against, depends on the feature level that you select in the license tool.

Platforms are AutoCAD, MicroStation and ArcGIS. The "Standalone" version (not requiring any other software to run) is always available, and MicroStation integration capability is also always included. Some products can be sold either with or without AutoCAD integration capability. Regardless, there is only one installation file per product - it will look for compatible platform versions and create shortcuts, but whether or not you can use those shortcuts depends if that platform is included in the feature level.

If your organization has an ELS or SELECT OpenAccess subscription, you will have access to all available feature levels. When opening the product, if multiple feature levels are available, you must select the one that the application will use. Starting with CONNECT Edition Update 2 (10.02.XX.XX and greater, available starting December, 2018), this selection is done in the Feature Level Selector. In earlier versions that use "SELECTserver" licensing, this is done in the Municipal License Administrator.

Element Limits

WaterCAD and WaterGEMS are licensed by the total number of active pipe elements that you have in a given scenario. For example if you have selected to use a license feature level of 10,000 pipes, then you will be able to compute a scenario that has up to 10,000 active pipes in the model. If there are more than 10,000 active pipes in the model, you will not be able to compute. Only the pipe elements are counted (which are connected between node elements such as junctions, pumps, tanks, etc) - lateral link elements are not currently counted. Here are some related articles:

HAMMER is only available in an Unlimited Pipes version. Meaning, you can compute a transient simulation (and initial conditions) for a model with any number of pipe elements. The exception would be an academic version which only includes a 5 pipe license.

SewerGEMS is licensed by the total number of active links that you have in your model scenario. Links are considered to be Gutters, conduits, pressure pipes and channels. The hydrology calculation won’t compute if you exceed the licensed number of links. If you change your active numerical solver to the GVF-Rational solver (StormCAD), the GVF-Convex solver (SewerCAD), or the Explicit (SWMM) solver SewerGEMS is still licensed by the number of links you have in your model. 

SewerCAD like SewerGEMS is also licensed by the number of links, which includes conduits and pressure pipes.

CivilStorm like SewerCAD and SewerGEMS is also licensed by links. Gutters, conduits, and channels are all counted. Just as SewerGEMS the choice of solver you choose is irrelevant to how the product is licensed. 

StormCAD is licensed by the number of inlets, (the catchbasin element.) Only catchbasins are counted towards that number, regardless of whether or not they have an attached catchment.

PondPack is licensed by the number of ponds in the model. 

FlowMaster and CulvertMaster do not have feature levels - you can simulate any number of worksheets/culverts in a given project file.

Inactive Elements

Whether or not inactive elements are counted toward your license depends on your version. With the CONNECT Edition, inactive elements do not count. For V8i and below, inactive elements are counted. See: Do inactive elements count against the license count?
