<div style="font-family: Calibri,sans-serif; font-size: 14px;">I think the filter you want is append attributes. The append attributes filter takes two datasets with the same topology and combines their fields into one dataset. The group datasets builds
an assembly of parts. Thus, your group datasets filter (if I understand correctly) has two parts that are coincident with each other.</div>

</div><div><div></div><div class="h5">

</div>
Hello,<br>
<br>
I´m new to Paraview and I am trying to perform a rather simple task I used to do with Tecplot. I have the flow field of a flat plate and I want to compare the boundary layer of my simulation with the theoretical velocity profile of Blasius. For that, both
the velocity tangetial to the plate and the distance normal to the plate have to be turn dimensionless. This is how I´ve tried to do it in Paraview:<br>
I open the solution file with the Tecplot reader, I add two Calculator filters to derive the dimensionless variables, then I join the two results with the Group Datasets filter. At that point I can find the two dimensionless variables in the Object inspector
when the GroupDatasets1 object is activated in the pipeline. The problem is that only one of the two new variables is displayed appropriately with "Display, Color by" or by applying the Plot Over Line filter.
<br>
<br>
Am I making some fundamental mistake? How would you people do this?<br>
<br>
Another funny thing is that for the Group Datasets object, I see in the Information tab that I now have twice as many points and cells. That´s not what I wanted and sounds pretty inefficient. I only want to create new variables for already existing cells.<br>
<br>
Any help will be greatly appreciated.<br>
<br>
Regards,<br>
<br>
