Description
The ground level of the 2D cell (ZC level) is below the 1D bed level. 2D cells selected by 1D/2D (HX) interface lines must at or above the bed level of the 1D channel. This error usually occurs when the 1D/2D interface line (HX line) passes through a depression that is lower than the bed levels of the 1D cross-sections.
The linking method when using 2D HX boundaries is described here:
Tutorial module 4, 1d/2d links
For a HX type connection, the water level from the 1D is transferred out to the 2D cells. If the 2D cells are below the 1D bed level, when the 1D model is dry the water level is set to the invert of the channel. If this water level (invert) is transferred from the 1D to the 2D, this would result in a flooded 2D cell. This could potentially allow water to be "created" in the model.
Suggestions
The 2D cell elevation controls when water can "spill" from the 1D to the 2D. Thick breaklines should be used to ensure that this elevation is correctly set in the 2D. This is documented in the tutorial model for 1D/2D linking here: Tutorial module 4, 2D breaklines.
