Hi

I have a problem with the following model.

When I try to run it in synthesim mode non of the graphs are drawn and if i press the graph icon in the left meny it says "unable to draw graph"

I'm not sure where that problem comes from - I suspect it has to do with the fact that the two compartment models Livestock and Aedis mosquitos affect each other.

I know that I have a unit problem with the "Number of Aedis eggs laid per day per mosquito" I have not managed to solve it so that it would satiesfy both equitations where it is used.

Any tips on how go ahead and get control of the model are appriciated.

Thanks in advance

For the units problem, change the units for both "number of aedis eggs laid per day per mosquito" and
"NOMINAL EGGS LAID PER DAY PER MOSQUITO"
to "Aedis mosquitos/Aedis mosquitos/day" (mosquito eggs/mosquito/day).

I had no problem running the model in synthesim mode. All graphs displayed fine. What version of Vensim are you using?

Hi
I'm running Vensim DSS forWindows Version 5.9 (Double Precision)

Thanks for the units help - solutions look so simple once you are shown it

Thanks I modified the units as suggested and that took care of the Unable to display graph problem too.
