Initial Lake Conditions Error

[aparkes]

Has anyone come across this error before? (see attached)

I'm running an unsteady model consisting of a single channel connected to a storage lake by two weirs. The model runs well at a 5min computational interval however falls over during post processing with the attached error.

If the model is run with a smaller computational interval then it runs ok but generates a number of spikes on the hydrograph and reports maximum iteration errors.

Any ideas?

The problem has been resolved, reducing the simulation end time by 10mins appears to have stopped Hec from reporting the error.

Most odd.

Just wanted to say thanks for following up w/ your solution, as I was banging my head against the desk w/ the same problem and your fix worked.
