Hi, I'm a final year engineering student and I'm a beginner with CFX. I'm getting an error when I try to run the solver that reads something like:Could not reference memory at "xxxxxxxx", memory could not be "read". If I take out the CEL expression and enter a constant value, the solver runs. However I am not getting an error in Pre regarding the expression

Thats a windows memory error message not a CFX error message.

Make sure you have enough ram and a big enough hdd swap space set.

You can also twiddle memory allocation settings in the CFX solver manager.

Thanks for that, will give it a try
