Information flow based algorithm of modelling

Witold Grabysz
A new concept of numerical modelling of discrete mechanical systems is presented in the paper. The method is based on a different organisation of information exchange between system elements than that commonly used. The idea was implemented by means of the object oriented programming. The way of overcoming the problem of numerical instability is discussed. Some examples are presented, where the values of eigenfrequencies obtained with the help of new method are compared with those obtained analytically.
