Hello everyone,

i need some advice regarding the IntegrateVariables filter. I want to integrate variables from an OpenFOAM CFD-Simulation along a line.

To do this i did the following:
- create two orthogonal slices which intersect at the line I want to integrate
- apply the IntegrateVariables filter on the second slice, that creates the line

However, the integrateVariables filter seems to not identify the line as a set of multiple data points. The information tab on the filter shows a range of 0 in all three dimensions and the output values make no sense at all.

I would greatly appreciate, if someone could give me some input on possible mistakes I am making. Thanks in advance!
