said:(10 months ago) Hi Dr. Saleh and others, I got an error message saying that the simulation failed. Error simulation scenario filter and waterway (The process cannot access the file. 'D:\ apexcont.dat' because it is being used by another process. I am trying to simulate the main cotton crops and cover crops in winter and filter strips at the edge of the field. I appreciate any help. Sincerely, Arjun Thapa NC A&T State University |
