I am trying to run a coupled hydrology-hydraulic, MIKE-SHE - MIKE-HydroRiver (MIKE 1D) model (2020 version, DHI). To get the MIKE 1D hydraulic simulation to run without stability issues I had to use a 5-second timestep. The coupled model seemed to run without a problem until it was about 83% through, had simulated about 5 years worth, when it showed an error message in the log and the programme closed itself.
The saved WM log file showed the following:
Error writing item file: C:\Users\User\Desktop\working\UpMols\Result\UpMols_13032019.she - Result Files\UpMols_13032019_ET_AllCells.dfs2 msheDFS Error: Unable to write dynamic item Error writing datatype, subtype, time: 1, 1, 44184.0000000000 Termination... Calling MIKE 1D with stop request after 31811040 time steps ... Ok 11:27:50 : Stopped after 82.8 % of simulation
My hard-drive is almost full after this run, so perhaps it is a drive space issue? If MIKE 1D needs a 5-second timestep, is my only option to find more drive space to get this to run?
