where are the results stored?
32-bit or 64-bit operating system?
steady or transient?
if you remove radiation, does it solve through?
any way to simplify the problem? 2 day solve time seems kind of crazy.
overall i think the error message is generic. you could check the solidworks kb for more specifics but i think this will be a version/service pack, study, model or computer specific issue.
Thanks for the reply.
- The results are stored in the same directory as the assembly file
- 64 bit
- I've successfully run the simulation with just convection. I have also ran it with a couple surfaces that have radiation heat transfer (in addition to a convection component). Everything ran correctly in those tests. I then simply selected more faces (admittedly a lot of them, but radiation is the dominant mode of heat transfer in my case) to include in the radiation portion. The only difference that I can see is that there are now more surfaces included in the radiation portion.
As a side note, the view factor calculation takes the most time. It makes relatively quick progess and then almost stalls out near the end. That part takes over a day. Then it runs through the normal calculations and stops when it's nearly done, displaying the above message.
Thanks for the SolidWorks KB reference. I'm still fairly new to simulation and am learning where to go for resources. I was able to find filed bug reports with similar error messages, but that is it.
I reduced the number of surfaces selected (to the really important ones) and am currently running the simulation again to see if it can make it. I'm hoping that this isn't a bug. I'll post back if it makes it or if I find a solution.
"same directory" > just want to make sure taht is local, not connected to a dropbox..etc.
also, i have seen this before with large files, how big is the CWR file and do you have enough HDD space?
regarding the SWX KB, i don't think you can direct link. what were the solution IDs? but I think what you're saying is the same as i mentioned, no particular cause, situation specific issues only.
The simulation made it this time.
I have no idea what caused the problem. The .CWR file is ~350MB but there are a large number of other files the simulation created, totaling to almost 5GB. The simulation took 2.5 days with roughly 1.5 days being the view factor calculations. Solidworks pulled about 7GB of memory for itself at the peak too.
As for the SWX KB numbers, one had solution ID S-058467, and the other had SPR# 638372.
If I ever do find a particular cause for this issue, I'll be sure to post back specifically what fixed it. I am leaning towards what Jared said earlier about this error message though; it was probably generic.
i'd get it out to your reseller so that they can report it to solidworks if necessary. there may also be ways to speed things up.
