applyPointBC() [1/2]

template<unsigned int dim, typename T , typename Memory , template< typename > class layout_base>

template<typename Mem >

__device__ __host__ void CartDecomposition_gpu< dim, T, Memory, layout_base >::applyPointBC ( encapc< 1, Point< dim, T >, Mem > &&  pt ) const

inline

Apply boundary condition to the point.

If the particle go out to the right, bring back the particle on the left in case of periodic, nothing in case of non periodic

Parameters

pt	encapsulated point object (it's coordinated are changed according the the explanation before)

__device__ __host__ void CartDecomposition_gpu< dim, T, Memory, layout_base >::applyPointBC ( Point< dim, T > &  pt ) const

inlineprivate

Apply boundary condition to the point.

If the particle go out to the right, bring back the particle on the left in case of periodic, nothing in case of non periodic

Parameters

pt	Point to apply the boundary conditions.(it's coordinated are changed according the the explanation before)
