How to get average flow quantities from oscillating steady solver results in FLUENT
3 Attachment(s)
I simulate one case using pressurebased, steady solver. Pressurevelocity coupling scheme is SIMPLEC. After 1,000 iterations all the residuals becomes flat, with the continuity residual around 3e1 (obviously not small enough to be satisfactory). Flow quantity (e.g. temperature) on one sampled point was also monitored. Temperature on this sampled point oscillates from 295 K to 312 K for every 20 iterations.
Now I want to calculate the average flow quantities (including velocity magnitude, temperature) over the whole fluid domain during those 20 iterations. Could anyone tell me how to do it in FLUENT?
PS: For transient solver in FLUENT, you can enable the option 'data sampling for time statistics' to average among time steps. But for steady solver in Fluent, is there similar way to average among iterations?
Pictures of scaled residual and temperature history on the sampled point are also attached for reference.
