Memory Problems
Memory Problems
(OP)
I am working on a large project and I am crashing SolidWorks several times a day. Each crash takes something like a half hour plus to reload. Sometimes the system explicitly states that it was run out of memory. Other times, it just hangs up, and I have to kill the process from Task Manager.
My model has 3958 components attached to it, with 732 parts and 281 sub-assemblies being unique. I have 571 top level mates.
My work directory is 1.28GB in size, and I probably have most of the files in it loaded. It is on my local hard drive.
I have attached files from elsewhere on our network, and their size may be significant, I am not sure. I know this is bad practise, but there is nothing I can do about it.
My computer has 4GB of RAM installed. According to Task Manager, I have 3538460KB RAM total, with something like 1.4GB used by SolidWorks. As of this moment, when SolidWorks claims it is unable to obtain required memory, Task Manager claims to have 1247384K memory available. 1.9GB of page file is being used.
After SolidWorks shuts down, my Available memory increased to 2.9GB, and the page file dropped to 600MB.
The OS is Windows XP, and it was installed several years ago.
I suspect that I am running out of RAM well short of my machine's 3GB+ capacity, but the articles I found on the internet are not clear on how to interpret Task Manager. Our sysadmin guys are telling me to put a service request in to SolidWorks.
Is anyone else here running large files like this? How stable are you, and how fast does your system run?
I am trying to figure out of this is a SolidWorks problem, or a machine configuration problem.

"Some M90 systems upon assembly at the dell factory received NVIDIA 2500M video adapters that may have been built with faulty memory supplied by Samsung".
I have had some minor issues, but they are becoming more frequent.

RE: Memory Problems
I've got 4GB of RAM and have never had a memory issue with this system, frequently getting my RAM consumption up as high as 2.0GB (not as high as yours). Go much more than that, and you'll need to switch to a 64-bit OS. (Can you believe we don't have a very suitable mainstream OS to run in 64 bits in 2008? Amazing.)

cleaning out the computer and freeing up resources/disk space/etc always makes the machines speed up a little more. hope that helps.

RE: Memory Problems
A star for you. Over 300 top level mates is our number one reason for slow assemblies and crashing. The second one is springs and lead screws which has been fixed.

RE: Memory Problems
Helixes (Helices?)?

RE: Memory Problems
Yes Helixes (Helices?) Big memory hog.
We used them for a couple lead screws.
Big mistake, never did need the detail.

RE: Memory Problems
If you are creating components that require detail (for the components drawings), create a second configuration that is a simplified representation of the component that can be used in the asm. This will allow you to load more components if they are simplified. and you will have the robustness of a complete design....
If you have any further questions or concerns please advise...
Take care & have fun!

RE: Memory Problems
I have done lead screws with two configurations, with and without the helix lead.
When I do coil springs, I do a revolve. This is good enough to make a clear assembly drawing.

RE: Memory Problems
We did call our spring fix "simplified".
Thanks
