Hello

I am pretty new on FEniCS.and I want to use FEniCS to solve a coupled set of PDE's including 3 different fields. These equations are coupled and should be solved to find three unknowns. I would like to explain my problem briefly.

Firstly I just want to solve these coupled PDE's in one dimension and then extend it to 2-D. Could you please tell me how I can deal with this problem in FEniCS? I would really appreciate you referring me to a solved example similar to my problem so I can come up with an idea to implement it in FEniCS. Thanks in advance for your time and attention.

How are you going to couple them in time? Solving for the chemical field simultaneously in the three equations or first solve it in the first equation and then use that value in the other two?
