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 />
