Re-opening FEA study causes SW "error - needs to restart"

John Sutherland Nov 27, 2011 4:10 PM

SW Premium 2009

SW seems to be working and FEA study seems to be working until I save and close the document. On attempting to re-open the document SW reports "error - needs to restart". Endlessly.

My workaround is to model the part then save as a copy and do the study on the copy and print the results before closing. Then I can open the original part and do another study on it.

As I am new to using FEA, this condition could have been present when I bought the product. I don't change hardware or software.

Simultaneously SW RX reports "error - needs to restart" when I attempt to run it, but when I ignore the message and request Windows cleanups that works. Looks like it can't connect to SW. It used to work.

I have seen Windows messages about low virtual memory but I dismissed them as I have 8GB of real memory.

Any suggestions?

On SW07 and SW09, we always found that if you have the Simulation add-in enabled but no parts open, then open a part, SW will, without fail, crash.

Are you leaving the add-in enabled after you've closed all parts? As this may be the solution to your problem.

  Spot on Dave! Sure beats paying a subscription to solve the problem.
  
  Here's what I did:-
  
  Open SW.
  Disable simulation on startup.
  Close SW.
  Open SW.
  Check Simulation add in - disabled.
  Open part document which previews a von Mises diagram; Model opens.
  Enable simulation; Study tabs appear.
  Click on study tab; loads and fixtures display so I re run study and von Mises diagram appears.
  Close document.
  Open document.
  ERROR
  
  I rest Dave's case.

    Excellent, glad it works!
    
    For what it's worth, the issue has been fixed in SW11 (possibly in SW10, we skip every other version so I've no idea), so we can now all be lazy and leave the add-in permanently enabled!

This crashing problem is happening with SW 2013, I gues the crashing problem still exist.
