How to use solid analysis's stress to be a function of another diffusion analysis's coefficient?

I am doing an analysis coupling of structural mechanics and classic PDE Convection-Diffusion Equation.
I make two physics and two study in the model and I can analyse them seperately.
Firstly, I will do the study1 (structural mechanics) and get von mises stress, "solid.mises."
Then I want to analyse the PDE Convection-Diffusion Equation (study2) in which the equation is da(∂u2/∂t)+▽(-c▽u2)+β▽u2=f
I hope that "da" can be a function the "solid.mises." that means the coefficient is different in each element according to their stress situation.
I search in the forum and it seems related to "dependent variables" but I can not find where to get the "solid.mises"
then I think maybe I should define and variable as solid.mises. but it still failed.
Could you please tell me that what should I do, thank you very much.
