Reversal of flow

I am modelling a reciprocal flow porous media combustor
I am solving a set of 3 PDE's that model combustion of methane in a
porous media combustor. I have modelled the combustor as a 1-D
interval of 0.5 m. I have used the PDE(c) module and have used 3
Convection - diffusion equation to model the PDE's. The dependent
variables are Tg (gas temperature), Ts (solid temperature) and Yp
(product mass fraction)
I want to mimic switching the direction of flow through the combustor
after every 100 s.
Essentially what I want is to:
a) Retain the last solution for Ts and use it as initial condition
after flipping it (so that it mimics flow reversal).
Can you suggest me a way of doing this automatically under program
control in comsol. I would really appreciate your help.
