differential equations
显示 更早的评论
To solve a problem by means of debugging it was not possible. The compiler has shown nothing... In an error it is written "either by reducing the fixed step size or by tightening the error tolerances"... How can I reduce the fixed step size?
And prompt please, can to solve my problem as it is described here http://www.mathworks.com/help/toolbox/simulink/ug/f11-69449.html My model solves system of the differential equations which are already resulted in the form of Koshi (18 equations). The error arises probably because there is no decision...

Fixed step size is a solver setting under Configuration Parameters on the Solver page. If you are running a continuous model with a fixed step solver and getting an error or a derivative going to infinity, you may have a singularity in the system.
Try running the model using a variable step solver.
