CFD results for previous iterations

Postby gkspl » Thu Dec 29, 2016 6:39 am

Hi all,

Is there a way to view CFD results for previous iterations?

E.g. there could be a case when simulation is going (without reaching to convergence) till 7000 iterations and it looks that it had better "Residual and Cell Monitor" results for iteration no. 6000. In that case, can I visualise/extract results of iteration no. 6000?

Hi Prashant,

Previous iteration results are not stored. It wouldn’t be practical due to the amount of data involved.
Also, previous results would not be reliable where solutions have become unstable.

Hi Luis,

The file size increases with number of iterations; that's why I thought, it might be possible to view results of previous iterations.
Thanks for the clarification on this.

Is there a more detailed documentation on "Convergence Difficulties and Troubleshooting" other than what is mentioned in DB help?

Hi Prashant,

At the moment the only information available is on the "Convergence Difficulties and Troubleshooting" online help chapter.

BR,
Luis
