Hi,

I'm working with oscillation problem.
Is there any function that returns the value of current time?
For example: F=sin(w*t)

Thanks,
Cristina

By "curret time" do you mean "model time" or real world time?

If its model time, then just use "time". To get the real world time you would have to either use an external function to get it, or maybe read directly from Excel.

I used "time" in my equations, but it didn't work.
The following message appears:
"The following inputs were not expected(but are used): Time."
I'm using Vensim PLE. Has Vensim PLE this facility?

Thanks,
Cristina

Thats just a warning message. You didn't have "time" on the sketch with an influence arrow pointing to the variable you were entering the equation for.

Tony.

Add Time to the sketch as a shadow variable - that is using the <var> tool.

Thanks. It worked pretty well.
