accessing previous time data in time dependent simulation

I am running a time dependent simulation and keeping track of two functions of time call them f1 and f2. I would like to be able to access previous time slices of the function f1 and pass them to f2 in the simulation. In other words at time t2 I need to access the value of the function f(t1) where t1<t2 and use that as an argument to f2 (ie f2(t2)=f2(f1(t1))). Is this possible?

Does anyone know how to do this?

John,

yes it is possible. I recommend looking into this blog contribution by Walter Frei: https://www.comsol.de/blogs/using-the-previous-solution-operator-in-transient-modeling/

Good luck Edgar
