error messege

Hi,
I am trying to simulate temperature changes due to a serias of short electrical pulses. I created a floor function fot the pulses ((t/0.250)<((floor(t/0.250)+0.00050/0.250)- 50microsecond pulses with a 250 millisecond interval) but when I compute the simulation I get an error messege that I may have reached a point of singularity. How do I fix the problem?
Thanks
Shirley

Hi
there are several threads on pulse trains, check the forum, I prefer to use the rectangle operator, and then combine with a analytical operator in repeat modus. This makes a smooth transition (à la Heaviside) so that your pulses are differentiable. Then do not forget to give a time range compatible with the time steps, and use time stepping "intermediate" and not "free"

Good luck
