Hi all,
Now I found a bug of the filter. My ParaView's version is 3.14.1. I define node names as below: > c--d > | | > a--b Case 1: a=1.0, b=0.0, c=0.0, d=0.0 Integration Value = 0.33333 Case 2: a=0.0, b=1.0, c=0.0, d=0.0 Integration Value = 0.16666 Case 3: a=0.0, b=0.0, c=1.0, d=0.0 Integration Value = 0.16666 Case 4: a=0.0, b=0.0, c=0.0, d=1.0 Integration Value = 0.33333 So Integration Values are calculated as (2*a+b+c+2*d)/6. I think it's not a good result.
