Hi All,

I am using Ptolemy to model and simulate a hybrid system. I started
with the thermostat model provided in demonstrations. Its working fine
but when it throws some exceptions when I change the model.
Here is what I changed, instead of same refinements for heating and
cooling states I have separate cooling refinement for cooling state. I
did appropriate changes on the transitions as well. Now when I run the
simulation (with animate execution debug option on) it goes to init
state then to heating. Now when it goes to cooling state it mmediately
throws an exception saying..

"The refined step size is less than the minimum time resolution, at
time 1.49 in example.Continuous Time (CT) Solver."

I dont know what does this mean and why is this happening.

Thanks,
Manish
