time running backwards

DFI filter runs backward and forward.

Thanks, Meteo. I know predictor-corrector numerical methods do this - by DFI you mean digital filter (Fourier)?
It's just that I've *never* seen this before in uEMS (many years), and I *always* watch progress of runs with tail -f... I was shocked, to say the least!! :lol:

Read run_dfi.conf there should be information about it and when it runs backward and for how many minutes. Lot of that is configurable.

Thank you *so* much Meteo - I've been a bad girl and haven't read as many of Robert's *excellent* script docs as I should have by now (mostly the numerical stuff). This is such an amazing project, when you think about it. I *did* notice in the docs somewhere that he uses the PGI compiler, which is great.

Best,
PattiMichelle
