different output issues

Post by bahri »

Dear,

I attach my model.

The 1st model separates outflow to A and B
and the 2nd one combines flow A and B.
My question is why the main reservoir levels are different
for different models?

They shouldn't be different. Can you post the .mdl?

Hi,

I will post the mdl soon.

What I see that when we water demand in A and B,
there many round-up numbers that let to
different levels of main reservoir.

For instance, when I combine water demand A and water demand B,
there are several round-up numbers, lead to different reservoir water levels

This is possible, especially if the scale of the numbers differs a lot. It's unlikely to matter in any real-world situation. It would be helpful to see your example though.
