WRF-ROMS-SWAN Coupling calculation error #250

Open DYB2363021436 opened 2 months ago

DYB2363021436 commented 2 months ago

When I use the WRF-ROMS-SWAN coupling calculation, after 1 hour of calculation in WRF mode, no more calculations are performed, and there are no errors in the logs, while ROMS and SWAN can be calculated for 1.5 hours, and then no more calculations are performed.

what are the time steps for WRF, ROMS and SWAN? the time steps need to divide evenly into the coupling interval. WRF dt = 20, ROMS dt = 40, SWAN dt =40 , Coupling interval = 200 is GOOD WRF dt = 15, ROMS dt = 40, SWAN dt =40 , Coupling interval = 200 is BAD check all your dt's.
