walberla::mesa_pd::mpi::ReduceProperty Class Reference
MESA-PD - Modular and Extensible Software Architecture for Particle Dynamics » Communication functionality for MESA-PD module.

Detailed Description

Reduce a property from all ghost particles to the corresponding master particle.

Attention
This kernel does not broadcast the reduced property to all ghost particles. Use BroadcastProperty or SyncNextNeighbors for that.
Usage:
The property which will be reduced can be selected by the Notification template (see ForceTorqueNotification). void reduce(data::Particle&& p, const Notification::Parameters& objparam) will be called to reduce the all incoming properties.
Precondition
  • the property is up to date on all ghost particles
Postcondition
  • the property at all ghost particles stays unchanged
  • the property at the master particle is the reduced one
