Fluid Flow (CFX) Error: The solver failed with a non-zero exit code of : 2

Hello,

I'm currently working on immersion cooling system and simulating to demonstrate bubble effects.

I have the above error message when I changed air diameter from 1.0mm to 2.0mm.

It was working okay with 1.0mm diameter and every other setting reminds the same.

How should I make of this error? 2.0mm diameter is too big?

Please refer to the attached image below for detailed settings:

There are 16 CPUs, 16 Heatsinks and cooling plate is surrounding the outer layer of the tank.

The tank is filled with fluid and air is injected from the inlets at the bottom of the tank.

For more information, please feel free to let me know.

Kind regards,

Nat

    Thank you so very much for your reply!

    I am not sure if the images below are clear enough for you... but I have a long list of errors.

    The error I was mentioning is for #16-20 dated Oct 11th.

    Does that mean the problem really is what's said prior ; duplicated boundary condition?

    I have corrected it and afterwards it was working fine so I though there is no more problem with the setting.

    Then, when I changed the air diameter from 1.0mm to 2.0, I could no longer continue the simulation.

    I will try your suggestion #1 and hopefully figure out what's causing the error.

    As for your suggestion #2, I did not make any changes in the geometry, so I can not really 'reduce the change'.


    Warm regards,

    Nat
