The calculator filter assumes the same number of points, whereas this is
not the case. Note that x1-x2 is undefined if size(x1) != size(x2).
Better way to go is to compare bulk values e.g. integrated pressure over
some distinc region or 2D intersection plots along some line.

Hi Dominik,
What I mean is that if I load :
grid1, data1
grid2, data2
and
interpolate data1 onto grid2
Then data2 is no longer in the list of variables (see attached picture),
and I can't use the calculator to do data2-data1

Yes I am doing something similar. What does it mean 'no longer have
access to data2'?

Hi,
I'm trying to interpolate a pressure field from one grid to another
and then compute the difference between the original pressure field
and the interpolated one.
So if I have :
grid1, data1
grid2, data2
I want to
1. interpolate data1 onto grid2
2. compute data2-data1
I try to use the Resample Dataset filter which seems to work for step
1, but then I no longer have access to data2! Am I doing something
wrong , or do I need to code up the filter so that it copies the data
associated with grid2 ?
If anyone has done something similar in the past -- please help :) !
