Detailed Description

template<unsigned int TDim>
class Kratos::BinBasedNodesInElementLocator< TDim >

REMARK: the location function is threadsafe, and can be used in OpenMP loops.

This class is designed to allow the fast location of the nodes of a fixed mesh with respect to a moving mesh. The utility relies on the creation of a static Bin that allows finding quikly the nodes of a fixed mesh that are inside each of the elements of the moving one. After the creation of the "BinBasedNodesInElementLocator", the user should call the function "UpdateSearchDatabase" or"UpdateSearchDatabaseAssignedSize(hmin)" to mount the bin and subsequently locate the points as needed An application of this utility can be found in

Parameters

pelement	The pointer to the element to be studied
positions	The indexes of the relative positions
Nmat	Shape functions
max_results	Maximum number of results to be searched
work_results	The point iterator with the points to be studied
work_distances	The iterator containing the relative distances
work_point	The node of study

Returns

counter: The number of iterations needed

UpdateSearchDatabase()

template<unsigned int TDim>

void Kratos::BinBasedNodesInElementLocator< TDim >::UpdateSearchDatabase ( )

inline

Function to construct or update the search database.

UpdateSearchDatabaseAssignedSize()

template<unsigned int TDim>

void Kratos::BinBasedNodesInElementLocator< TDim >::UpdateSearchDatabaseAssignedSize ( double  CellSize )

inline

Function to construct or update the search database The cell size is requested as input parameter. This action reduces consideribly the searching procedure. One possibility is to give the dimension of the mesh.

Parameters

CellSize

The bin cell size
