I'm able to successfully run the BandpassFilter example, but as it stands, the results appear empty.

The data.txt file:

Hi @dan-gies, I am definitely not an expert but removing/commenting the line Exec Solver = never under Solver 2 in file Filter_Zhai.sif should do the job. As far as I understand Solver 2 computes the actual fields so it should be run.
