Is anyone acquainted with this error message from MIKE Hydro River?
[color=red]Unexpected simulation launcher exception. Please see log file for exception stack trace. Exception message: 'Failed loading data from MIKE Hydro bridge (DHI.Mike1D.MHydroBridge.MHydroBridge): myfilename.mhydro'

I do not find any further information on the error, and I am not sure what MIKE Hydro Bridge actually is. Can anyone help?

Thank you

Hello,

I just had the exact same error !

Have you found an explanation?

Thank you

Did you work out what the problem was?  i have a similar error in Mike Urban +

I fixed it by creating a new boundary (pointing to a local time series) and a new simulation.
