Background

This article provides access to Validation / Certification documents for the above listed Hydraulics and Hydrology (OpenFlows) products. These documents are sometimes required in order to widely adopt software. They show that the software's hydraulic results match published or known results.

Certification Statement

The below document certifies that the Hydraulics and Hydrology products (listed in the header block of this article) have been validated by manual calculations or by a comparison with a previously validated computer program. The statement "validation data is on file" means that the results of our automated tests (comparing results) are stored internally for the Bentley development team to review.

Verification Documents

CivilStorm V8i SELECTseries 2 (08.11.02.65)

The below .ZIP file contains a verification document showing how CivilStorm's results (using the Explicit numerical solver) match known results (based on EPASWMM). The data files are also included. Note that this validation was done using version 08.11.02.65 - future versions could potentially have slight changes in the numerical solver that could make the results out of date. However, these data files have been checked in later versions of CivilStorm, up to SELECTseries 4 at this time.

HAMMER V8i SELECTseries 3 (08.11.03.19)


The below .ZIP file contains a verification document showing how HAMMER's results match published results. The data files are also included. Note that this validation was done using version 08.11.03.19 - future versions could potentially have slight changes in the numerical solver that could make the results out of date. However, these data files have been checked in later versions of HAMMER, up to SELECTseries 5 at this time.

If you are inquiring about QA&R for certification for the nuclear industry please note that HAMMER does not offer the same type of ‘nuclear certification’ as AutoPipe. We do have the aforementioned document and files that can be downloaded below, however, if you'd like to compare the results yourself. If you need verification of other customers in your industry that use HAMMER you should contact your Bentley account manager.

Important Notes about the Model Files

General - Note that the calculation of the initial conditions is not required with these model files, as they use custom pre-entered initial conditions (by way of setting the "Specify Initial Conditions?" Calculation option to "True", then values were populated in the respective initial conditions input fields). So, after opening the file, you only need to click the Compute button (not the Compute Initial Conditions).

Test Case 01- when utilizing the data file for test case 01, the included quadrantcurves.txt file needs to be placed in the installation folder. You may want to back up your existing quadrantcurves.txt file. Be sure to place the file in either the root of the HAMMER8 installation folder if using the 32-bit version of HAMMER (C:\Program Files (x86)\Bentley\HAMMER8), or the "x64" (C:\Program Files (x86)\Bentley\HAMMER8\x64) subfolder, if using the 64-bit version. If you are unsure of the version being used, go to Help > About HAMMER and look in the lower-left corner (64-bit will be designated here if you're using the 64-bit version).
