Hi
I am trying to run a 3D fluent model on my school's cluster using FLUENT 12.1
However I am constantly getting a 'Stack backtrace error'. I did a bit or research and I found out that this is possibly caused due to memory allocation. Since I am using a script file and dont have access to the gui, I dont know how to fix this error. Anticipate a quick response. I am attaching the script file and the error log in case you need to take a look at them...thanks..aar

yes and I finally got it to work...but however I have one problem...my solution has a constant error of turbulent viscosity exceeded and also reversed flow. The reversed blow goes away after around 150 iterations but the turbulent viscosity seems to rise and eventually causes my solution to diverge...any comments on that are most welcome!
