How can i downgrade a .wtg file?

Hi 

I'm trying to open a .wtg file in the WaterCAD version 10.00.00.50 but it pops up this error: " The model you are trying to open was saved in a newer version and cannot be opened in this version"

I still have credits in this version so i dont want to upgrade it.

There is a way to downgrade this file to open in my WaterCAD?

Thank you

  • Option 2: Export to EPANET (Water) or EPA SWMM / LandXML (Storm and Sewer)

    If the user is not able to upgrade to your version, the best workaround for the Water products (HAMMER, WaterCAD, & WaterGEMS) would be to export the model to the standard EPANET format (File > Export > EPANET). This format can be opened in most older versions (File > Import > EPANET). For example in older v8i versions, you can import EPANET via File > Import > Network. Note that there are limitations with this method such as only being able to export one scenario, and other items described in this wiki article .

    The best workaround for SewerGEMS and CivilStorm would be to export the model to the EPA SWMM format (File > Export > SWMM v5). After that the SWMM file can then be opened by most older version of the software (File > Import > SWMM V5). As with the EPANET for the water products, you may also run into some limitations or have the potential to lose some information in the process of the export/import. In SewerCAD and StormCAD, you can export the model to the LandXML format (File > Export > LandXML) and import the LandXML file into the older version of SewerCAD or StormCAD.

    there's only this solution?

  • I followed that instruction but i couldn't import anything from the Epanet file. And it shows up this 2 user notifications messages

  • Hello Miguel,

    Can you please upload the .INP file and the original WaterCAD model from which you exported the EPANET file for our testing?

  • Hello Miguel,

    I tried to compute the model in EPANET as well, and there were error messages in that program as well. There are a few issues keeping the model from computing. I would recommend validating the model first, to review the issues. 

    First, there is a tank without any elevation data. If you look at the tank T-1, there is no operating range for the tank. This data will need to be included. 

    Second, there are disconnected nodes in the system. This appears to be because some junctions are not connected to pipes. This can sometimes occur when creating a model. For instance, if ModelBuilder was used and junctions were created at a tee of a couple of pipes, the junction will be overlaying the pipe and not actually connected to it. You can use the Batch Pipe Split tool to help fix these.

    If this doesn't help, it might be good to see the original WaterCAD model as well. If you can provide the .wtg.sqlite file, we would be able to check that model to see if there are any issues too.

    Regards,
