Hi, I ran a 2D unsteady model. The model ran for ~ 186 hrs. It also gave volume accounting error and % error. However, resultant maps were not generated. The error shows: 0 maps generated “planname”, store map error “planname”, object reference not set to an instance of an object. I ran the same model in two different work stations. Both the models failed to generate output maps. What could be the possible reason for this, and how to rectify the same? I am not sure if I have to re-run the model as it takes lot of time.
