Does anyone have an example on how to use NeuralPDE.jl with Coupled PDEs ?  
All the examples I have seen only use one function, I would like to solve 8 coupled equations with 8 functions. So, if an example with more than one function would be useful.

Did you look at the system of PDEs tutorial?

Thanks, that seems to be the example I was looking for. I will try it out tomorrow.
