Thanks Bob - what I mean is that if you multiply a pulse train, it simply magnifies the amplitude. i.e, say you had a pulse train of height 1 that lasts for 2 hours - if you multiply this by 2 (i.e the multiplier constant was 2), you get a height of 2 that lasts for two hours. What I actually need i...

Pulse train
Good morning all! I have another simple question for you experts. I have a series of irregular pulses (of time step 1). What I want is to convert the pulses of time step 1 into pulses of time step 3. Obviously, simply multiplying by 3 will multiply the magnitude by 3, which is not what I want. I hav...

Totalling values over a day - for one year
Good afternnon. I have a question that is probably quite easy for you experts to answer! I have a series of pulses over the course of a year (the Time Step is one hour). If we zoom in to 1st April, for instance, the pattern could be a pulse (of one) between 9:00-12:00, 14:00-17:00, 20:00-22:00 and n...

Comparing the value of a previous time step.
Hello. I have a variable that outputs a series of irregular pulses - for example: 01010011011100 - the time step is 1 hour. However, I don't want 2 consecutive 1's - so I want the above series to read: 01010010010000 What I was thinking was, is there any way of comparing the previous time step value...

Periodic Random Numbers
Hello all. I have a question that might very well be simple to answer (I'm fairly new to Vensim, so am learning as I go along). From what I understand of the Random functions, they give a random number every time interval (in my model this is set to 1 hour). However, what I want is to have a pulse o...

Repeating a pattern of pulses.
Hello again.
I've created a pattern (of the utilisation of various training devices) using a series of pulses. What is the best way to repeat this pattern (over 52 weeks)? I want to avoid having to manually input all of the pulses.
Thanks

Subscript and Variables
Hi there. I'm new to Vensim so I'm wondering if somebody could assist me wrt Subscripts. I've defined a subscript and placed a Box Variable in which I want to define the elements of the subscript as other Variables- i.e., I want the elements of the subscript to be variables - is this possible? I've ...
