block. The flowsheet also included a recycle stream to enable algorithms associated
with waveform relaxation method.
y = 0.5 · ({0.5 · sin({sin(t) + 2} + {sin(2t) + 1} + y) + 1}).

Figure 8 (left) shows the outcomes of modelling the given equation in Dyssol and
MATLAB. It can be seen that the results obtained in both systems coincide.
To analyse the accuracy of calculations of the simulation system in dynamic mode,
continuous fluidized bed spray granulation with external classification of product
described in [47] was used as a reference process (Fig. 9). It includes one dynamic
(granulator) and three steady-state (two screens and a mill) units enclosed into one
recirculation loop. The granulation process in a fluidized bed apparatus is represented
