Water Quality Errors

Error message:

2025-11-16 22:41:05: WARNING: Courant criteria was violated in time step 0, simulation time '2016-01-01 01:00:00'. Maximum Courant number: 1.649e7 at ''Branch 124', 150.00 m'. The criteria was was violated in '75.3277'% of the points in this time step. The engine used a more stable but less accurate method at these points. (AD_WAR_CourantViolatedFirst) 2025-11-16 22:41:09: Exception: Index was outside the bounds of the array.
