SIMULATION OF BILIARY SYSTEM BY FEHLBERG METHOD WITH ACCURACY AND STABILITY CONTROL
The 6-stage Fehlberg method of five order of accuracy is considered for purpose of a hybrid problem solving. Inequalities for calculation accuracy control and for numerical schemata stability are constructed. The author gives formula for choice of integration step based on accuracy and stability taking into account behavior of an event function. The results of biliary system modeling are given in the paper.
