Yifei, Glad that helped. If memory becomes critical, you could write a Programmable Filter that created array Loc by shallow copying array coords – this would sharply reduce the memory footprint of the Loc array.
Next time I’ll ask you for help!

I created Loc using vector array coords. Then I have no problem finding the points using Find Data by specifying certain Loc. Thanks for the help.

However, perhaps you can use vector array coords – this is Paraviews internal array of point positions. You could use this to create Loc after you read your file into Paraview – your filesize would not increase, although you would use some memory for the duplicate of coords (I assume running Calculator does a deep copy, anyone able to correct me) So, read in file, run calculator on it – add Point Data Array Name of Loc – from the Vectors dropdown add coords to expression. Now you will have a vector called Loc and my earlier queries will work. I could not get the queries to work directly with the coords vector array – maybe someone else knows how to do that.

Hi Dennis, Sorry that I wasn't clear about the data file. The "Loc" DataArray is not included in the original data. I simply copy&paste the "Position" DataArray and re-named it "Loc" in order to find data based on its location. This is a workaround and it works just fine for small data files. However, my original data is quit huge and I have to do the copy&paste for thousands of files to make the workaround work. Also file size will be increased significantly by using this method. Since the "Position" information is already included in each data file. I am wondering if there is a way to access it in "Find Data". If so, I don't need to replicate it to create "Loc".

I DL’ed your file and proceeded as follows Edit/Settings/General/Auto Convert Properties checked (On) Find Data Find POINTS in test_data.vtu Loc(0) is >= 0.009 Run Selection Query Extract Selection This correctly extracted the 1 point met that requirement If I change to a query of (Loc[:,0] >= .008) & (Loc[:,1] >= -.0004) then it correctly selects the single point that meets that criteria. Perhaps the difficulty is because you haven’t set Auto Convert Properties Hope this helps.
