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

+--------------------------------------------------------------------+

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.

Default Ansys CFX- Topology estimation factor error

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!

ghorrocks is just really niceghorrocks is just really niceghorrocks is just really niceghorrocks is just really nice
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.
