|
|
</P>
|
|
<P>The data exchange model performs the data exchange between the DEM code and the CFD code. The twoWayOne2One 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 a more sophisticated mapping scheme than twoWayMPI / all2all and scales much better for large systems and many cores. The DEM run is executed by the coupling model, via a liggghtsCommandModel object.

<P><B>Restrictions:</B>
|
|
</P>
|
|
<P>Must be used in combination with the engineSearchMany2Many locate model! Use the "one2one" cfd datacoupling option in fix couple/cfd in LIGGGHTS!
