I have a DIAG speed trouble when I tried to run a long-period (~20 years) WRF-ROMS coupling simulation. But my simulations always crashed after about 6~7 years. I tried to change the time step, the relaxation time scales, with or without the tide forcing... All of these could not solve the speed trouble. The range of v is -6~28m/s and the picture only displays -6~8m/s.
