another node. On the other hand, the agent that has arrived at a given node installs
there the information it has brought.
This procedure is repeated for the nodes lying on the trajectory along the cooling
pipe R .
The example of the simulation of the temperature field during the cooling of the
cast with the use of the cooling medium (at two different moments of the process)
is presented in Fig. 5.30 . The course of temperature in time, for the cooling without
the flow of the medium ( v =
0) is presented in Fig. 5.31 a, and with the enabled
flow of the medium ( v >
=
4 s is presented in Fig. 5.31 b.
Comparing the temperature courses, it is clear that the application of cooling results
in the stabilization of the differences in temperatures between the point p 1 and the
point p 2 .
The above solution concerning the simulation of the solidification process of the
casting contribute to the improvement of the methods used for the design of the
cooling systems, and for the control of cooling through the changes of the flow of
the cooling medium. They are an example of the application of the agent approach
in technologies of metalwork production.
