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

have you configured your all nodes good ?

[amoolraina]

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!

I am not mechanical engineering. but IT related person to resolve or help out within parallel computing over linux or windows.

So how did you manage the error? as i am still getting the error with 8 cores shared memory (same PC)

hi all

I am also having the same problem of stack error. I am attaching image file of that. Please suggest a solution for this.
