Hi Dinesh,

Please find attached script for computation of Uniformity Index (UI) in Acufieldview.

Hi Kamlesh,

Invalid scalar function error.

Let me know to rectify the error.

Hi Dinesh,

if you are using latest version ie 2017 no need to use script.

UI id directly available as a output in acuProbe under Surface Statisctics. as shown in below image.

Thanks Ravi!!!!

@Altair Forum User @acupro  are there any updates you can provide as to how to calculate uniformity index in HyperWorks CFD 2021.1 ?? Is there a similar output for volume-averaged uniformity index?

The Plot utility from the Solution ribbon has essentially the same functionality for surface results uniformity - through surface statistics

I'm not aware of anything built-in to handle volume uniformity.  What is your use-case, and what do you want to calculate?

Thanks. Ended up stumbling across this. Grouping surfaces via setting up a monitor prior to solving was helpful too.

I'm simulating flow through porous media and want to look at uniformity of a given velocity component. Volume uniformity has been helpful for this type of application in other commercial packages in the past. The definition used for a component "v" for all cells "c" in the volume "V" was:

I don't have much experience with AcuSolve, etc. prior to HW CFD; would an external script be needed to implement the above metric?

Indeed, the collections for Surface Output are quite handy in HyperWorks CFD, as the collections can be independent of other collections.

I'm told you may be able to do something approximate for volume uniformity with a python script accessing the solution database directly - but that is not my area of knowledge...
