Differential equation system in Anylogic

Question

I have to model a differential equation referenced to another one, i.e.

d(Pa-Pl)/dt=flow1 dPl/dt=Pl-theta

where flow1 is some function depending on Pa and theta is a constant.

The question is: How it is possible to model this equation systems in Anylogic?

Thanks in advance

Answer 1

I find this question a bit weird, but here it is:

where:

flow1=dPadt-dPidt

and

dPidt=Pi-theta
