2 days ago The issue is that you have not attached your oil to the spill. You just need to include the line substance = oil, or just substance = gs.GnomeOil(filename="troll_EC00721.json"), without defining oil.
oil = gs.GnomeOil(filename="troll_EC00721.json") spill = gs.surface_point_line_spill(num_elements=1000, start_position=(start_x, start_y), release_time=start_time, end_position=(start_x, start_y), end_release_time= start_time + gs.days(3), amount=50, substance = oil, windage_range=(0.025, 0.025), windage_persist=-1, name='My spill')

Dear all, I want to see weathering, but I can't to do that. I use wrong way or I made abnormal environment? I made my environment with conda. 'https://gnome.orr.noaa.gov/doc/pygnome/installing.html'

I use this script. No error cord occur, but there are no weathering in json files. In addition to this question, I want to see weathering result in shape file. Can I see weathering result in shape file?
