However, if the upper layer starts to move towards the bottom layer, then this
phenomenon will have an influence on the process of heat spreading in both bodies,
particularly at the point of their contact (Fig.
5.25
b). Two phenomena should be taken
into account in the simulation of this process—the phenomenon of heat spreading
and the phenomenon of two bodies relocating relative to each other. To realize the
simulation of the phenomenon of relocation, we may use the agents acting in the
environment created by the nodes of the grid.
5.5.2 The System Realizing the Simulation
of the Displacement of Bodies
A pilot version of the system has been developed at the Department of Computer
Science at AGH University of Science and Technology in Krakow [17]. This system
consists of agents acting in the environment of the network (Fig.
5.26
). The main
idea of this solution is a change of the role played by the nodes of the grid.
According to the classic approach to the simulation, the nodes of the grid rep-
resented the points of the body in which the simulated thermal conductance takes
place. Due to this fact, the temperature of a given point of the body in a given node is
memorized and it is changed in time (the time of simulation) according to the process
of heat spreading on described with the use of appropriate equations.
In this approach, the nodes of the grid represent the points of space. The body
whose specific point corresponds to a given node of the grid at a given moment is
represented by corresponding information stored in this node.
It means that it is not only temperature that is stored in the node but also the
parameters specifying physical properties of the point of the body which corresponds
to this node.
