i get this error in cfx pre when i start the solver but not when i save the definition file.

Value of 'Number of Passages in 360' in object '/TURBO POST DATA/TURBO POST COMPONENT:R1', '0', violates its lower bound, '1'.

but the no of passages in the rotor is 12 and i passage is being modeled and i am using time transformation for the unsteady simulation.The solver exits with the following message

please suggest what i can try.

have you double checked if
"Value of 'Number of Passages in 360' in object '/TURBO POST DATA/TURBO POST COMPONENT:R1', '0', violates its lower bound, '1'."
If Pre reads it like '0' and not '12' then there's something wrong with the setup.
Can you post your ccl?

I have had the same issue as well with no solution so far.

Hello Everyone,

I am trying to simulate centrifugal pump in CFX. I have this error set the topology estimation factor to be 1.2. I have already changed that to 1.2 , but still the error continues.
I have checked my mesh quality which was good in terms of Aspect ratio, orthogonal quality, Skewness etc.

My solver runs when I set the value to 2. Does this effect convergence or my results.

Any leads would be appreciated!

If it runs with 2 then just use that.

But this issue is a warning that CFX is having a hard time with something in your simulation. It could be a difficult interface, complex boundary patch or something like that - it is likely to be something in your mesh which is more complex than normal.

Hi ,

I am doing one condensation analysis over a cylindrical surface but when I have tried to run facing this error stated below continuously after lot of trials .

Kindly suggest

Does your calculation stop, or not? Because you only show a warning, not an error.
