# begin by setting up input parameters

frontback - frontBackNEW - V2 - function: swashSimSetup
Add:
grid = inputDict['modelSettings'].get('grid', '1D')
to input parameters and add grid = grid to 162-163:
wavepacket = prepdata.prep_spec_phaseResolved(rawspec, version_prefix, grid=grid, runDuration=runtime, nf=nf,
waveTimeList=DT.datetime.strptime(wrr.dateString, wrr.dateStringFmt))
Otherwise wavepacket returns none because version_prefix must equal base AND grid must equal 1D for prep_spec_phaseResolved to prep a SWASH wavepacket.
