getDynamics()

template<typename T , typename DESCRIPTOR >

virtual Dynamics< T, DESCRIPTOR > * olb::AbstractCollisionO< T, DESCRIPTOR >::getDynamics ( )

pure virtual

Implemented in olb::ConcreteBlockCollisionO< T, DESCRIPTOR, Platform::CPU_SIMD, DYNAMICS >, olb::ConcreteBlockCollisionO< T, DESCRIPTOR, Platform::CPU_SISD, DYNAMICS >, and olb::ConcreteBlockCollisionO< T, DESCRIPTOR, Platform::GPU_CUDA, DYNAMICS >.

set()

template<typename T , typename DESCRIPTOR >

virtual void olb::AbstractCollisionO< T, DESCRIPTOR >::set ( CellID iCell, bool state, bool overlap )

pure virtual

Set whether iCell is covered by the present collision step.

Parameters

iCell	Cell index
state	(De)activate for this dynamics / collision
overlap	Cell index in overlap (set dynamics but do not collide)

Implemented in olb::ConcreteBlockCollisionO< T, DESCRIPTOR, Platform::CPU_SIMD, DYNAMICS >, olb::ConcreteBlockCollisionO< T, DESCRIPTOR, Platform::CPU_SISD, DYNAMICS >, and olb::ConcreteBlockCollisionO< T, DESCRIPTOR, Platform::GPU_CUDA, DYNAMICS >.

weight()

template<typename T , typename DESCRIPTOR >

virtual std::size_t olb::AbstractCollisionO< T, DESCRIPTOR >::weight ( ) const

pure virtual

Returns number of assigned cells.

Used to determine the dominant dynamics to choose e.g. which collision operator to vectorize or to prefer in GPU kernels.

Implemented in olb::ConcreteBlockCollisionO< T, DESCRIPTOR, Platform::CPU_SIMD, DYNAMICS >, olb::ConcreteBlockCollisionO< T, DESCRIPTOR, Platform::CPU_SISD, DYNAMICS >, and olb::ConcreteBlockCollisionO< T, DESCRIPTOR, Platform::GPU_CUDA, DYNAMICS >.
