ERROR 10340 - Structure max open width MUST be defined for linked zone structure type.

Description

Linked zone structures require a maximum open width to be specified. This value is used to to complete hydraulic stability checks and is required to be manually specified for linked zone structure connections. This applies to structure blocks with Flux Function == options where the structure width cannot be inferred from the flux function geometry.

```

Suggestions

Add the Max Open Width == command to the linked zone structure block. This value should represent the maximum width of the structure opening when fully open.
