Coupling Settings

In this Section we present an overview of the coupling settings. If not stated otherwise all dictionary files mentioned in this chapter are located in the constant folder.

Special handling of gravity

The gravity set on the DEM side by the enable_gravity command is transferred to and also applied on the CFD side when using twoWaySocket. The user may overrule this setting by providing a different gravity setting in the file constant/g.

Note

If using a solver based on a formulation involving p_rgh (e.g. a compressible solver) the presence of constant/g is required. The settings on CFD and DEM side should match in this case. A warning will be displayed if they deviate.
