I can't offer much advice, as I don't use SolidWorks Simulation much and have only done so on small parts or assemblies, but I would use the Windows Task Manager and Resource Monitor to see what your RAM usage is. Perhaps you are pushing the system into swap space when you add another part.
Thanks for the reply. Its not near to maxing my ram, right now using ~1.3 gigs during one of the freezes.
I've been trying several things, such as pack-&-going to a new directory, deleting previous simulation files from the work folder, defragging...
I guess I should start eliminating parts until I can isolate the problem.
Do you remember what part you added to your model when this started occuring?
I did several things this morning. Deleted some mirrored component assembly features and re-added them, adjusted some sketch dimensions, and added some mates.
I did accidentally unsuppress a bunch of features I had previously suppressed, but they should all be suppressed again. I might need to go through the tree item by item and check everything.
I believe I might have fixed it. One of my mirrored part's reference had been suppressed, and for some reason it decided to move .0000000001" from its mating surface, and apparently that was causing bonding issues. It still takes a few minutes to mesh and run, but its much more manageable now.
Eh, its not quite fixed. When I bring everything back into the simulation, it still takes 5-10 minutes to mesh, and 5-15 minutes to start the simulation once I press run. If anyone has any more info on optimizing assemblies for simulation, or how to speed this up please add a reply. Thanks
Any chance you can get on SW2014? Meshing and simulation has performance improvements in SW2014.
Maybe get your VAR your model to see if the improvements will be a benefit for you.
Where are the files stored?
Simple blocks...etc mesh in an expected period of time?
How many parts are we taking about?
How many elements are we talking about?
How many contact sets?
What you describe sounds reasonable if you have a large Mixed mesh model with contact sets to define contacts.
