Add time dependent equations to the physics builder

Dear All,

I am trying to use the physics builder to model the thermoelectric effect. As it happens there is a step by step tutorial for this exact example available; the problem is that it only explains the steady state case and expressing them in the weak form, whereas I need to solve for the time dependent case.

The equations for this case are:

row*C*dT/dt + del.q = Q

and

del.J = - (drow/dt)

Does anyone know how to enter these equations in a form Comsol will accept?

Thanks
