Member Function Documentation

◆ DefragmentFreeList()

void ChDistributedDataManager::DefragmentFreeList ( )

Internal function for cleaning free list that tracks space for shapes.

Should not be called by the user.

◆ GetLocalIndex()

int ChDistributedDataManager::GetLocalIndex ( unsigned int gid )

Returns the local index of a body, given its global id.

Returns -1 if the body is not found on this rank.

Member Data Documentation

◆ initial_add

bool chrono::ChDistributedDataManager::initial_add

Indicates that the system is undergoing its inital setup.

Allows for some shortcuts by assuming contiguous valid data.
