Ventana software support forum

I resolved that by using a constant rather than an input/output control

ok, I figured that out (I created a shadow variable for Time and connected it to Pressure with an arrow). Now I'm trying to create a slider called Amplitude and connect it to Pressure with an arrow, but having no success. How would I do that?

I would like to create a variable called Pressure and set it equal to 10*COS(2*PI*Time). How do I do this in Vensim?
