Global Material Properties tab of the ADH Model Control dialog

This window is part of the ADH model control dialog (ADH | Model Control... command). It is accessed from the Model Control window by clicking on the Global Material Properties tab.

ADH contains parameters that apply to all materials and parameters that are specific to (and must be defined for) each material. The parameters found within the Global Material Properties tab apply to all materials.

The bed layers specified here are applied to all mesh nodes and can only be overwritten at the nodal level in the Bed Layers Assignment window. When bed layers are created or deleted here, nodal bed layers are defaulted or deleted, respectively.

Parameters (Untitled group box)

Enable wetting/drying limits check box and the associated Dry depth and Wet depth positive real number edit fields correlate to the optional MP DTL card. If the water depth of a node is below the Dry depth, then the node is completely dry and is not included in the ADH shallow water equations. If the water depth is above the wet depth, then the node is included in the equations. A water depth which falls within these two depths will include the node in the equation with a restricting factor.

Constant

Uniform background viscosity positive real number edit field correlates to the MP MU card.

Gravitation acceleration positive real number edit field correlates to the MP G card.

Density positive real number edit field correlates to the MP RHO card.

Wetting and Drying

Enable shock capturing/stability procedures below depth is check box and the associated wetting and drying process. When this toggle is selected, ADH performs extra calculations for all cells with depth values less than the specified minimum to stabilize the process. As the specified depth value increases, extra calculations also increase and model performance decreases. When this option is selected, the Depth edit field is enabled by SMS. In this field specify a positive real number correlating to the optional MP DTL card.
