Simulation (computer modeling) is<br />
a method for solving the tasks changing<br />
their states in time. The models of real<br />
experiments are composed on a computer<br />
and the course of model behavior is compared<br />
with real experiment (real modeling<br />
<strong>pro</strong>cess course). Parameters and model<br />
structure are changes to be the model<br />
behavior the same with observed real <strong>pro</strong>cess<br />
(model verification). The result is<br />
recognition of the real <strong>pro</strong>cess rightfulness<br />
and further the ap<strong>pro</strong>ved computer model<br />
can be used for real authenticity <strong>pro</strong>gnosis.<br />
The simulation software makes possible<br />
easy simulation models compilation. The<br />
simulation methods are used at many science<br />
fields in this time. The simulation<br />
is used at medicine praxis for simulators<br />
compare for example for surgical execution<br />
training.<br />

The simulation software is divided<br />
according its using in follow way:<br />
Continuous simulation makes possible<br />
to compare models changing their state<br />
continuous in time and do not change<br />
their structure, for example MATLAB,<br />
SIMULING. The differential equation solving<br />
is typical for the continuous simulation.<br />
Discrete simulation makes possible to compare<br />
models of systems witch change their<br />
states and structure in finite time points,<br />
for example GPSS. The software is used<br />
for economic and administrative tasks.<br />
Combined discrete continuous simulation<br />
makes possible to compare models witch<br />
change their states continuous in time<br />
and the structure in finite time points, for<br />
example software CDCSIS, which will be<br />
used in this article. Combined simulation<br />
makes possible to compare continuous<br />
and discrete models too. The combined<br />
simulation is used for solving of differential<br />
equations witch change their structure<br />
in time.<br />
The software CDCSIS is assembled as<br />
library of <strong>pro</strong>cedures at language C++.<br />
A simulation model is compiled in this way:<br />
blocks in language C++ is <strong>pro</strong>grammed<br />
which make disposable calculation specific<br />
situation (discrete block) and particular<br />
calculation which is <strong>pro</strong>vided under certain<br />
situation (continuous block). A calling<br />
of the library <strong>pro</strong>cedures schedules<br />
calculations according to blocks and/or<br />
finishing of the calculation, starting and/or<br />
finishing of integration and graph output<br />
or animation.<br />
The top of article is not instruct with<br />
any software and/or get to know a simulation<br />
using at some branch but to show<br />
a simulation advantage and simplicity on<br />
3 examples and makes a <strong>pro</strong>pagation of<br />
this scientific method. The continuous<br />
