template<typename GhostLayerField_T>
class walberla::pe_coupling::discrete_particle_methods::CombinedReductionFieldCommunication< GhostLayerField_T >
Special communication routine to += the values in the ghost layers and update the ghost layers.
Reduces the field with += to obtain the values from the block neighbors' ghost layers and add them onto the corresponding values inside the domain. This is followed by a regular ghost layer communication to synchronize the ghost layer values.
This functionality is typically used to synchronize the solid volume fraction field and the interaction force fields, after they have been filled by a distributor.
For more infos on distributors, see src/field/distributors.
