Two solid phase, but only one solid pressure?

Hi Team,

I am trying to do some mixing and segregation study using TFM. It seems that in theory for each solid phase, there will be a solid pressure in the momentum equation. However, only one solid phase can be output. I have also tried to output p_s(:,1) and p_s(:,2) using two reactionrates arrays. The results show that p_s(:,1) equals to that obtained from that specfied in the GUI, while I am not sure about the value of p_s(:,2). I have attached the associated files. Could you please help me figure it out?

Thank you very much.
