Inlet structure unstable

[John Clark]

Hi,

I’am having some troubles with a inlet structure, despite the solver having some troubles finding the solution (always use 20 iterations), it seems correct.

It has elevation controlled gates. The upstream BC conditions is stage hydrograph and the downstream BC is storage area.

Please see some pictures below:

Do you have any idea to solve this issue?

Thanks,
John
