Flow Sim crashing with an assembly?

Alex Rich Nov 13, 2012 2:05 PM

Hi guys, I'm using flow simulation on a rear wing I designed for my school's Formula SAE car. I have two elements and two early iteration endplates. For whatever reason, when I go to start flow-sim for the assembly, solidworks decides to crash out. We're using the 2011-2012 student version of solidworks. The flow simulatino seem to work fine when it's used for a single part. The rear wing I'm doing the simulation is fully defined as well. Any help is much appreciated!

Thanks

At what point does it crash out? Does it crash when you add Flow in or does it crash once you start to run the simulation?

I have found that assemblies can become corrupt over time and in some instances have been forced to go back to an older version of the assembly I had archived.

If that is not the problem and it is crashing during adding Flow in, I would check for interferences and invalid contacts. Those can cause crashing.

  whoops! I wasn't too specific with a few things.
  
  It seems to be crashing out when I click the wizard button, or if I try to hit new, i can get past the first window then it decides to crash. The assembilies seem to be built, mated correctly, and fully defined, it doesn't seem like these are any issues on that end.
  also for what it's worth, I've tried this on three different computers, my personal laptop (not the best specs), a new school computer (corei7 processor, more ram than it knows what to do with, etc.), and an old school computer (not great, but still runs everything well)

    You do have the full Flow Simulation license correct? You are not using FloXpress are you?

      Correct, I'm using our school's license which I've gotten to work with other parts. It seems to work for a full car we have, it may be an issue with the assembly, I may try to put another one together and see what happens with that

        Yes I would try making a fresh assembly.

        with a new assembly, it seems to be working, thanks!
