keeping variable history for DAE problem

Hi,

I am solving a heat balance coupled to an algebraic expression for conversion of a particle. The algebraic expression is caluclated based on the temperature history, T, and the derivative temperature history, dT/dt, cf. the attached pdf for the equation.

My temperature ode solves the dT/dt.

Is there a way, that I can store ode output and differential for the entire past variable range, since I need it for evaluating my function I?

Thanks

The temperature equation is dependent on the algebraic equation that is why I need to solve it inside the ode function script for each time step.
