[?] Switch between two drag models at same simulation - multiphaseEulerFoam
 

Hello,

I am trying to simulate a column with porous media using multiphaseEulerFoam, in v9. It consists in define three phases, gas, liquid and solid, and use the solid phase as stationary.

But, at the top of the column there are just liquid and gas and at the middle and bottom of the column, liquid, gas and solid.

I would like to know how to set the solver to use SchillerNaumann at the top (liquid and gas region) and AttouFerschneider at the bottom (liquid-gas-solid region).

Thank you,
Raphael
