Autodesk SSA - What SWMM 5 Version (5.0.013?)???

[Anonymous]

What version of SWMM 5 is Autodesk SSA running?

My guess is 5.0.013? Even with SSA 2016.

Does anyone know of the last update? I know that LID controls have not yet been included (SWMM 5.1).

I am trying to match SSA with PCSWMM and 5.0.013 appears to match, but not any of the later updates...

Regards,

Conrad

SSA should match 5.0.21 or 22, with the exception of new elements introduced from about 5.0.13 on.

Do you mean that it uses that version of SWMM for both the hydrologic runoff calculations, AND the hydrodynamic hydraulic routing calculations?

[Charlie.Ogden]

Yes, SSA is using the SWMM 5.0.021 engine for the EPA SWMM hydrology method and for the routing methods and other components... but the LID treatment units in particular have not been added in.

Thank you for clarifying that!

Any change to this? Was SSA updated to the 5.1.013 engine? I am getting different results in SSA2019 and 5.1.013.

Issue I have right now is with the hydrology.

Highly unlikely.   There have been a bunch of 5.1 changes, including getting to 5.1.013.   

We are about to release the next build of InfoSWMM with the 5.1.013 engine which was a lot of work and we keep the engine update.

[Matt.Anderson]

John -

Remember - SSA 2019 was released last year in March/May time frame.   EPA released SWMM5.1.013 in September 2018.

Short of time travel - impossible for 2019 to have been future proofed.

I should note that "we" in the prior reply is Innovyze.  

[jmayo-EE]

I didn't mean to come across as snarky Matt. It is just an inquiry. This is my first look at the EPA app and did not check their release date. I just need to explain the discrepancy for a presentation.

[Matt.Anderson]

John -

Your best bet for the discrepancy would be to look at the EPASWMM release notes and identify the changes that affect hydrology.   (Don't worry about the snark - it hit me about an hour after the first post (which is beyond editable time) that its impossible.)

Send me an email and I should be able to assist.

To best find the overall difference between SSA  (last new feature was 500104) and the latest version of SWMM (which as of August 2018 is 51013)

The current SWMM 5 version is 5.1.015 but there will be an EPASWMM 5.2 soon (2021).

Good afternoon, Autodesk Team,

Can you please confirm which version of EPA SWMM does SSA runs on? I have not been able to locate this is information in the product help or about buttons neither in the release notes in the Autodesk website.

In particular I would like to know on which version of EPA SWMM does SSA 2023 and SSA 2024 run. The reason being is that I am running a test of comparing the same model in SSA 2023 and EPA SWMM 5.2.3 and the results are not converging.

Thank you in advanced.
