1. MF::Database::Node
The basic container that stores data is
Node structure
MF::Database::Node.
MF::Database::Node stores basic data for all computing nodes (fluid and boundary) i.e. values of particle distribution function and a pointer to its MFThread.
The key parameters for LBM calculations are the directional values of the probability density distribution function of the momentum for a fictitious particle (material point) in a nodeForAutoThreading, stored in microflow's arrays
MF::Database::Node::FQ19.
2. MF::Database::Thread
MFThread is an object of class
MF::Database::Thread that collects some number of
Nodes of the same type which shares the same additional properties i.e. name, initial and boundary values and they are processed in the same way by functions during a pre-collision and collision steps. Pointers to those functions are kept by the
MFThread object.
Nodes are stored in a std::vector<Node> type dense array
MF::Database::Thread::m_NodeArray_Ptr. Each computational
Node has to belong to exactly one
MFThread. Now, MFThread also contains propagation table of pointers to nodes divided into two parts and an array of original nodeForAutoThreading coordinates in sparse geometry.
