to reset iteration number in FLUENT
 

If u are fed up of the large iteration numbers. (this happens generally when parameter sensitivity of the same case file is set and iterated further.....)

Try this ...

Step1. Read Case/Data file for which the iteration number can be restarted

Step2. save data of all variables in the domain using INTERPOLATION. (File> Interpolate) For Eg. "xyz.ip"

Step3. Initialize the same case (Solve> Initialize> Int)so the iteration counter is set to 0

Step4. read the interpolated file (File> Interpolate> Read and Interpolate) for eg. "xyz.ip"

Step5. Start iterating !

Iterations number will start from 1, and also the output fles will be store with the same iteration number.

Thanks

or just type solve/montiors/residual/reset/yes in the TUI!

Re: to reset iteration number in FLUENT
 

Sorry cadaei, ur method will just show the reset in iteration number, but if u see the contors, or write the history files u will get have the old iteration number.

Dear Mohan R,

is there any additional software that needs to be installed before I try this method?

Thank you.

Retrieve solution from a given iteration
 

You can try this as well: File\Solution files then choose one of the saved iterations to restart calculation from and click "READ" to retrieve the solution, you can press "calculate" to continue calculations (Before this you should have done: Calculation Activities\Save every - choose a number of iterations (for ex. 50 to get solution saved every
50 iterations. By doing so, you'll be able to retrieve solutions at 50 - 100 - 150 - 200 .. etc iterations).

Hope this will be helpfull

In Ansys Fluent V19.2 you can also resent the iteration count by clicking 'solution' tab, and under Reports click 'residuals'. In here change the 'iterations to store' to '0' and 'plot'. This appears to reset the iteration monitors.
