dataExchangeModel twoWayMany2Many command

Syntax

Defined in couplingProperties dictionary.

dataExchangeModel twoWayMany2Many;
twoWayMany2ManyProps
{
    liggghtsPath "path";
}

  • path = path to the DEM simulation input file

Examples

dataExchangeModel twoWayMany2Many;
twoWayMany2ManyProps
{
    liggghtsPath "../DEM/in.liggghts_init";
}

Description

The data exchange model performs the data exchange between the DEM code and the CFD code. The twoWayMany2Many model is a model that can exchange particle properties from DEM to CFD and from CFD to DEM. Data is exchanged via MPI technique using the many to many mapping scheme. The DEM run is executed by the coupling model, via a liggghtsCommandModel object.

Restrictions

Must be used in combination with the engineSearchMany2Many locate model!
