Is anyone running Adams for larger (Monte-Carlo) sims and what hardware do you recommend, or any general machine specs. Do you run on Linux or Windows? - Thanks

    Using Adams/Insight you can export the files for all the runs. Then easily batch it out on several computers. Limitation is number of Adams licenses. I have often highjacked laptops from colleagues to run part of the run over night or weekends.
    You would ask Insight to export all the adm and acf files.
    run_001.adm run_001.acf
    run_002.adm run_002.acf
    ..
    ..
    ..
    run_3000.adm run_3000.acf
     
    Assuming that you have 3 Adams licenses that you can use, you would copy run_001 to run_1000 to one computer, run_1001 to run_2000 to the second and run_2001 to run_3000 to the third.
    On the first computer you create a batch file "run_all1.bat" with the content (unfortunately looping is not a strong thing in bat files, sometimes I do this in python instead or windows command files):
    "C:\Program Files\MSC.Software\Adams\2020_711253\common\mdi.bat" ru-s run_001.acf
    "C:\Program Files\MSC.Software\Adams\2020_711253\common\mdi.bat" ru-s run_002.acf
    .
    .
    .
    "C:\Program Files\MSC.Software\Adams\2020_711253\common\mdi.bat" ru-s run_1000.acf
     
    Do the same on the other machines for the respective runs and kick off all the runs from a command window.
    You can also do this on one computer. Just do it in different directories. In the Adams Settings & License --> ASolver --> Preferences, set the numThreads to a suitable value (I have 12 threads available, so I would in this case set numThreads to 4.
     
    After all runs are done, collect all results files in one directory. When Insight exported the run files it should also export a cmd file that would loop over all the results files and extract the objectives.
     
    This is the principle, there might be some holes in my description as I have not done this for a few years now.
     
    So regarding computer: As fast processors as you can get your hand on. At least 12 threads and 32 GB memory. Unless you have very complex Adams models with lots of flex contacts, that should be enough. But can you get more, do so.
