Dear forum members,

I'm looking for a possibility to create a geometrically defined volume that I can later perform calculations on. Or to put it in other words, I want to create a rectangular cuboid within my fluid domain that I can refer to for additional calculations, e.g. calculate volume averaged properties.

So in my fluid domain, I can create a volume via locations and limit this volume in one dimension (e.g. z-dimension). However, I can't add any more limitations regarding the x- and y-dimension. Any ideas how this can be done?

I probably could create a group of iso clips from respective planes and average the results outside CFX, but this is not straight forward and not a “real” volume averaging, so I hope there is a better option.

One idea:
Make an expression defining your boundaries e.g. if(x>1[m],1,0)+if(x<2[m],1,0)+ ....
Make a variable of your expression.
Make an iso volume of your variable and plot it at value = 6

Can you please describe in detail.i am performing free surface flow with water being seperated into two halfs by an obstruction I wish to find out the volume passing through right side of the obstruction only.how can I do that?
