External function adn feedback loop with time depend solver

Please login with a confirmed email address before reporting spam

Hi,

We are users of COMSOL ver 4.1. We would like to simulate motion DC motor using AC/DC time depend model , especially commutation process as a function of time and the rotor position. We know that in previously version 3.3/3.4 Comosol enabled feedback loop with each step of time depended solver and user defined function . This can be written in Comsol script. The 4.1 version provide that models can be written in JAVA and we are wonder it is the same possibility to write user defined function which is coupled with the time step solver. We also know that Comsol 4.1 enables to use external function but we don’t know how to use it. It is possible to receive a simple example of this kind of problem.

Please help us
