I have two sets of output files i.e., rm2turbPipe0.f00001 and rmsturbPipe0.f00001 from Nek5000. The files are with the same mesh and I want to use them to calculator. I had followed the previosu topic [Calculator from different field sources?](https://discourse.paraview.org/t/calculator-from-different-field-sources/176), but my _Append Attributes 1_ and _Append Attributes 2_ (please see the attchment) stay under the two different files, so that the calcualtor cannot to combine them together. I am not sure it is because my operation, the version of Paraview or the output file of Nek5000. Could anyone give any suggestions? Much appreciated.

On the `Pipeline Browser`, with both rm2turbPipe0.f00001 and rmsturbPipe0.f00001 selected while holding down the Ctrl key, then `Append Attributes` filter must be applied.
