walberla::lbm_mesapd_coupling::MovingParticleMapping< PdfField_T, BoundaryHandling_T, ParticleAccessor_T, ParticleSelector_T > Class Template Reference

Detailed Description

template<typename PdfField_T, typename BoundaryHandling_T, typename ParticleAccessor_T, typename ParticleSelector_T>
class walberla::lbm_mesapd_coupling::MovingParticleMapping< PdfField_T, BoundaryHandling_T, ParticleAccessor_T, ParticleSelector_T >

Maps the moving particles into the simulation domain and updates the mapping.

Cells that are inside a particle, will be marked with the 'obstacle' flag. 'Inside' means that the cell center is contained in the particle. Thus, a containsPoint function has to be available for all particles/shapes.

Cells that in the last time step were inside the particle but are now outside of it, i.e. the particle has moved, will be marked with the 'formerObstacle' flag. The 'formerObstacle' flag is used in a second step by the PDFReconstruction class (see PDFReconstruction.h) to re-initialize the missing PDFs. Afterwards, the 'formerObstacle' flag is removed and the 'fluid' flag is set.

It is not strictly required that the mapping has been initialized with the mapping kernel from below.

The 'mappingParticleSelector' can be used to include/exclude certain particles from the mapping.
