Time constants

Post by Nabil »

Hi

Please help me with this issue.
The flow from some of the stocks in the model consists of three factors say ABC where A and B represent levels(unit individuals) and C is 1/(invidual*month). C is of the order of 0.001 and the smallest time step setting is larger than this value, is that a problem, or is it (BC) that counts. I have tried different time steps and the error message appears first when the time step is 0.125 but below that the curves look the same

Thanks

Hi Nabil,

I don't really understand your question, but all flows need to have the same units of measurement. If they do not, there is a formulation error.

What is the error message you are seeing?

Hi Bob
Sorry I mixed things up, I realised that after sending the mail, the message is warning for overflow, thanks any way

All the best
