Hello Guys!

I need the help in order to know how I can insert this function as source.

Thanks for your help

This is very similar to
http://www.ventanasystems.co.uk/forum/v ... f=2&t=6682

r = if then else ( time >= 0 :AND: time <= 10^6 , 10^(-4) , 0 )

Thanks my friend!

I have another dude in this case for this function the Vensim model is on this way ( see the image please), the variable "flujo de entrada" is a fluence variable when I defined the ecuation r = if then else ( time >= 0 :AND: time <= 10^6 , 10^(-4) , 0 ) is necessary that I insert an auxiliary variable called "tiempo", is it correct? and what are the possible settings for this auxiliary variable called "tiempo"?

Sorry, I don't understand what you are asking here.

Well,

In relation to the model this equation r = if then else ( time >= 0 :AND: time <= 10^6 , 10^(-4) , 0 )corresponds to an input stream, at the moment of entering it into vensim this equation depends on the time for which it is necessary to declare the variable time as auxiliary variable, is this correct or what values ​​would have to take the variable time?

The vensim model was previously attached.

Thanks!

You do not need to declare time (it is already declared in every Vensim model).

Thanks I run the function and it is ok!
