    Solidworks and RAM

    Michael Mixa

      Good evening all,


      I am pretty new to running simulations. I am working on a project that requires us to run some stress analysis on several frames and verify that the lifting eyes and associated hardware will be able to withstand the weight of the frames and all the items mounted on the frames when lifted. In order to save time and processing, I am focusing only on the top portion of the frame and have simplified the frame to the point that if I were to limit this even further, the results would be considered garbage. I am able to mesh the frame, however when I run the simulation the simulation crashes during mid calculation stating that there isn't enough memory for Solidworks to finish running the simulation.


      However, the thing is my system is pretty robust. I am running Solidworks 2012 64 bit on the following:


      • Windows 7, 64 bit
      • Intel Core, i7-3740QM @ 2.70 Ghz
      • 32 GB of RAM


      I have the task manager running to see the amount of RAM that is being utilized and I noticed that the Solidworks is utilizing 6 GB of RAM at most at the time of crashing. The rest of the 24 GB of RAM is being left untouched even though the program states there isn't enough memory.


      Does Solidworks have a built in limit to how much memory it can utilize?


      Thanks in advance for any assistance.

          no limits inside the software but windows controls allocation of RAM to programs. in my experience, windows can see simulation as not the highest priority (especially if you're working on other things at the same time) and not allocate the ram. there is really nothing you can do about this. you can make a smaller page file but generally the best methods are to make sure your page file is on the fastest driveit can be on and make sure you've spent time making your simulation setup as good as you can. for example, are you using solids or beams for your frame?

              I've limited the number of programs and windows open while the simulation runs to the solidworks program itself, the folder that the file sits in, and the task manager and the same error persists. The frames were created utilizing the weldment feature or is there something I would have to additionally modify in the simulation set up?
