The principle of simulator coupling is often
described as simulation backplane technology,
because simulators are coupled by
a data bus performing the communication
between the simulators.
Because certain basic knowledge about
the simulation methods applied here is important
for successful processing of a simulation
task, below is a brief review of the
fundamentals of SIMPLORER’s numerical
algorithms and simulator coupling.
Although in reality all processes of a complex
technical system run in parallel, in
simulation a sequential calculation of
these processes must be done, because
most readily available computers have
only one processor. Therefore, one must always
keep in mind during modeling that
all the components of a modeled system
are processed one after another.
