dataExchangeModel_twoWayFiles command

Syntax

Defined in couplingProperties dictionary.

dataExchangeModel twoWayFiles;
twoWayFilesProps
{
    couplingFilename "filename";
    maxNumberOfParticles scalar1;
    DEMts scalar2;
};
  • filename = filename of the VTK file series
  • scalar1 = maximum number of particles in DEM simulation
  • scalar2 = DEM time step width

Examples

dataExchangeModel twoWayFiles;
twoWayFilesProps
{
    couplingFilename "vtk_out%4.4d.vtk";
    maxNumberOfParticles 30000;
}

Description

The data exchange model performs the data exchange between the DEM code and the CFD code. The twoWayFiles model is a model that can exchange particle properties from DEM to CFD and from CFD to DEM. Data is exchanged via files that are sequentially written/read by the codes.

Restrictions

Developed only for two processors, one for DEM and one for CFD run.
