Long Time to open The model_SewerGEMS

The SewerGEMS model is shared on Bentley drive is taking very long time to open, in spite of the Tracking feature is closed the model is really annoying with the long time opening, that with the latest version, I also tried top test that on the SewerGEMS SS4 (10.04.00.145) and still taking long time till the model appears (more than 15 minutes to open). that on the work station computer with SSD drive.

  • Hi Mohamad,

    Is "JI Model-Rv06" the correct model? If so, I cannot reproduce the issue - the model takes seconds to open for me, using SewerGEMS 10.03.04.53. 

    Since the model was last saved in version 10.02.01.04, the "schema update" step will take some time to upgrade to the new file format, but this still takes a matter of seconds for me.

    This sounds very similar to the issue you reported earlier this year: Very long time to open the SewerGEMS model

    In this previous discussion it was found that you may only be encountering this issue when computing a large number of scenarios with very large output files (tens of gigabytes), along with storing the model on a slower mechanical hard drive.

    1. Can you confirm that the model is indeed stored on a solid state drive?
    2. Can you confirm that there is adequate storage space on that drive?
    3. Are you computing a large number of scenarios and saving the results before opening the model? (which ones?) You had only provided the .STSW and .SQLITE files (no saved results). If so, can you confirm that the model opens quickly if you place a copy of the .STSW and SQLITE in a new folder on your local drive and open from there? (ruling out both output files as well as other supporting files like DWH)
    4. Can you confirm that you are not running out of memory (RAM) when opening the model? Try opening task manager > Performance (or track the memory usage for sewergems.exe in the Details tab). If you have a large number of output files being loaded, they could take up significant memory.
    5. Have you tried clearing out your Windows temporary folder? (open File Explorer, type %temp% in the address bar press enter, and clear out the Bentley folder)
    6. I noticed that panning around your model is a bit sluggish due to a very large number of catchment vertices. Does it help if you uncheck "Catchment" in Element Symbology, save and reopen the model?

  • Dear Jesse,

    To answer the above questions, yes. It is SSD Drive, has good storage, is not running out of memory and the temp folder is empty.

    we re-tried that on the latest SS3 and it did not take a long time to open, it seems the problem is trying to use the pre-released SS4, I hope you try that model on the SS4 before releasing that officially.

    see the screenshot when it runs with SS4

  • Thanks, I see what you mean now in Update 4, build 10.04.00.145 (limited release version) as well a newer version 10.04.00.151. (I am not seeing the problem in 10.03.04.53)

    The problem seems to be in the custom updates during the schema update process, likely because the model was previously saved in an old version. I am not sure why this takes so long (I have reported this to our developers as defect #1052472), but this is a one-time delay from the database structure upgrade process and should not occur again after you first save the model in Update 4.

  • Thank you Jesse - I am sure your developer fix that in the official released.

    would you please share with us version 10.04.00.151, so I can see if that takes shorter time on that.

  • Hello Jesse - just as additional observation regarding your point #6 above, the catchment is delaying the process also.

    The model after saving it to SS4 is faster to open, however in that version it is lagging when preform zooming and pan with the catchments, hope that can be consider.

    Appreciated,
