Optimise algorithm use of selected grib files
Does the Optimise function use an “amalgam” of the selected grib files? If so does it give equal weighting to all the selected grib files? I’m a newby to this forum so apologies if this appears elsewhere.

Re: Optimise algorithm use of selected grib files
If you have multiple grib files the routing algorithm selects a single grib for each data type at every time step.
It looks for the newest - highest definition data for every time step. It does not average the data or pick a single grib for each type.
It is generally recommended unless you have well thought out what you are doing not to load a mix of weather models when doing routing. The results you get might not match your expectations.
