Troubles with export to Simulink model as General dynamic block

Tue, 09 Mar 2010 17:14:09 +0000

Hello, everyone!
I tried to export the model of synchronous generator - generator_2d.mph from AC/DC Module/Motors and Drives of Model library, but it doesn't work. When I try to simulate this model from Simulink it reports about 2 mistakes:

Model error "Java exception occurred:
Exception:
com.femlab.jni.FlNativeException: Matrix is zero
Messages:
Matrix is zero"

and

Block error "Error in 'untitled/COMSOL Multiphysics Subsystem/S-Function' while executing M-File S-function 'femsfun', flag = 1 (derivatives), at time 0. MATLAB error message:
Java exception occurred:
Exception:
com.femlab.jni.FlNativeException: Matrix is zero
Messages:
Matrix is zero

Stack trace:

at linearization.cpp, row 2146, ()

at com.femlab.solver.Linearization.newMatResSolve(Native Method)

at com.femlab.solver.Linearization.newMatResSolve(Unknown Source)",
when solver is ode45

and another mistake:
Model error "Memory allocation failure", when solver is ode15s

When I export this as "General static", all work good! And in this way I even able to get diagramms of magnetic values time dependend. But for some reason electrical values is possible to get only in General dynamic export...
Please help me to make a working general dynamic export of generator_2d to Simulink and to avoid the errors!
Thank you a lot!! With best wishes,
Konstantin.
P.S. Sorry for my English.
