ANSYS Fluent 14.5 x64 Crash many times

I just downloaded ANSYS 14.5 x64 version. I am working with FLUENT however fluent is crashing many times suddenly when it is calculating. Usually after 300 iterations. I also faced with the same bugs in 14.0 x86 version. Is there any service pack or similar things? Or is there anybody knows why?

Best Wishes

Can you exclude a hardware (broken memory, broken fan,...) or a microsoft (windows) problem?

I vave the same problem too, but not after 300 iterations. (Windows 7 Ultimate x64)
Have you a legal license?

Thanks for reply...

I dont have any broken hardware, I am using it on my laptop. I think the problem occurs from ANSYS itself.

As a student, I am using cracked one. :D (win7 Home basic x64) However, I dont think it is about cracked or legal licence, since I read before in another forum, someone complains I am paying $30000 and it crashes many times.

I had this problem too.

Only way I could get it to stop is recreate the project from scratch. I made all the parameters and settings the same but made some changes to the model in designmodeler. I did not work out exactly what it was about the model that caused it to crash. I have a suspicion it was related to subtracting a volume from the fluid more than once.

me too
I have the same problem with Ansys Fluent 14.0
I can workaround the problem doing this: i start the calculation, after 100-200 iterations i cancel the calculation then i close fluent and then re-open all the stuff resuming the calculation.
