I am trying to compute the difference between two variables that are stored in two different solution files. The mesh and geometry are identical between the two files. After reading the documentation, I tried to use the
AppendAttribute filter but see weird behavior. Before
merging the two solution, I renamed the density variable to be densityNew and densityGold using a calculator filter.
I attached a screen shot showing the profiles of the two variables. The densityNew variable is not properly appended. I am not sure what is happening here. It looks like the ordering of the coordinates does not properly propagate when the
AppenAttributes filter is used in this case.
Any help would be appreciated.
