I've been following the ADM743 FSAE tutorial and while completing WORKSHOP2/Part2 (Simulating a Full Vehicle Assembly). I get an error in the message window stating the model isn’t defined? So where and when do I need to define the model?

  • Hi,
    On what page do you get stuck? did you succesfully completed Part1?
    Can you please fill up your user details, please?
  • Hi Alexis,
     
    Part 1 was successfully completed, but there was an error when loading the full FSAE model. The tires weren’t recognised? It also looks like there is no test rig?
     
    when you say user details, what and where? My user profile?
  • Capture
    Yes in your user profile, please.
     
    Sorry to disagree, if you had an error in Part1 you did not completed the tutorial correctly. Please, try loading your vehicle again but this time without errors. You can try with other vehicle models if you prefer.
    Thanks,
  • Thanks Alexis, I tried to load the vehicle several times, but no change. The tutorial in the help files worked when I tried it a while ago. I will attempt it again, but not sure why the tire templates aren't loading with the FSAE model?
  • Hi,
    It is likely that you modified your assembly and saved without noticing. A simple way of finding out is opening it in Notepad++ (or similar software) as follows:
    • Find the path to the assemblies in your FSAE database
    C:\...\fsae_2016.cdb\assemblies.tbl
    • make sure that the subsystem information USAGE is correct
    Capture
    Compare this to other vehicles available in your installation database:
    C:\"installation directory"\acar\acar_concept.cdb\assemblies.tbl
     
    Good luck
  • Alexis, the assemblies look the same, but when I load and run the MDI_Demo_Vehicle everything works. I've saved the message window contents at the end of the Sim (in notepad) with both the MDI Demo Vehicle and the fsae_2018 full vehicle and compared the difference. The fsae_2018 model seems to fall over at the Adams Tire stage stating:
     
    Could not find a SAMPLE_PERIOD argument for model.fsae_powertrain.powertrain_gse.
     
    The next repeating error is:
     
    This command cannot be processed until a model has been defined.
    Maybe you need to add a FILE/MODEL=pathname, OUTPUT=prefix command to the command (*.acf) file.
     
    The files are there but probably with no data in the due to not getting past the first stage of Adams Tire?

    Hi,
     
    It seems to me that the model you are loading is not the one in the tutorial:
    AdamsCustomerModel
    The correct tutorial model should look like similar to the one below:
    AdamsTutorialModel
    When I load the tutorial model I get this:
    tutorial model loading
    Your model cannot be simulated because as soon as Adams tries to load the tires it fails as shown in the log file you attached. So:
    1. Check you are loading the tutorial model and not your prototype vehicle.
    2. Check your model loads correctly as per the tutorial example, if it doesn't investigate.
    3. If you don't understand the issue compare your database with that of someone else.
    Thanks,
  • Hi Alexis,
     
    I've downloaded the 2012 and 2018 fsae databases. I'll run through the tutorial again and hopefully get them to load successfully. I'll report back either way.
     
    Thanks.
  • Hi Alexis,
     
    It would seem the problem is related to not being able to load any fsae model? I tried the fsae_2012 database and it wouldn't load the full vehicle due to the front suspension not being found. I downloaded the fsae_2018 database (from the tech article) and get the same issue with not loading the tires? What's curious is the warning states the 2017 tires cannot be found from the 2018 database? This warning comes up about 16 times before the load will complete with the error listed above?
     
    Have you got a different source to download the fase database from?
  • Hi Woz,
     
    I have fsae_2016 and it works correctly. I'm almost certain that your database is being modified or got corrupted in some way. Can you share the error, please? Alternatively:
    • Have you tried removing your database and downloading it again?
    • Have you tried in a different machine with another database?
    • I don't have a way of providing you with a new database, sorry. Maybe you could open your assembly file in a text viewer and check that the USAGE folders for each item failing to load are pointing correctly, this applies for assemblies and subsystems.

    Good luck
