Hello,

I am currently working on a VAWT simulation in Fluent for my masters degree.

I set the TSR as an input parameter and the power coefficient as an output parameter.  

I was wondering if I can make a convergence criteria via an expression as such:

[Cp(n+1) - Cp (n)] / Cp (n)  < 1% , then the solution is converged and the solver will stop

where n is the iteration, and Cp is the power coefficient.

Is it possible to do so? If yes, does anyone know how I can write this?

Thank you so much

Regards,

Hi,

The convergence condition facility allows you to set convergence on the solution that are based on the values from report definitions.

You can check ansys user’s guide for more details: 35.16. Convergence Conditions (ansys.com)

Hope this helps you.
