Ventana software support forum

Hi Guys I'd like to know how do you set an equation so to get whole numbers.

and I can't use the help vensim manuals as it says they are not found. I tried downloading the software again but didn't work.

Many thanks,
Gaston

Floating point error computing - r Z1 - at time = 85.000000.

I believe that this menas that the value from rz1 is to high. So then what should I do and How do I do that???

Hi Guys, If you have the time I'd appreciate some help with the outcomes of this model. This is a model about population. Population extends in an are which is divided in three zones. POI is a variable which affects population growth and population movement between zones when POI values are very hig...

thanks indeed guys!:)

Do you think this is correct?

MAX (0:AND:8000, movement A+rep-mort-surv-movement B)

So the population will keep in between the values of 0 and 8000. Am I understanding?

thanks karan!!

Hi how's it going,

I want to set a maximum value for a variable (maximum population grouth must be 8000, so it should not go further up than 8000). How do I set that up?

Cheers!

so what value should I use? a zero, a five, any number?

Hi there, if anyone is there.

I'd like to link two models, both in different views. I believe I have to use a tool called shadow variable tool. Interesting to know where that tool is!!!

Cheers for helping me out

no rush I sorted out

What does it mean?

ERROR: Fix floating point errors before entering SyntheSim mode.
ERROR: Floating point error computing - mort AZ1 - at time = 22.000000.
Trying to save the results anyway

the values are wrong or the structure of the model?

Hi guys, trying to understand the way of using this random uniform equation. I understand that: RANDOM UNIFORM( {min} , {max} , {seed} ) min is the minimum value and max the maximum value. For example 0, 1 but what is the seed thing about??? It's driving me creazy as I read the help and it obviously...

Hi guys, first time here.

How do you set the minimum population so to not get negative numbers?

Cheers
