Hi All,

I am trying to model surface reactions in a porous media. I want wall surface reactions at the walls of the porous media and gas phase reactions within the fluid bulk. However, I can only specify one reaction mechanism at that region in 'Cell Zone Conditions'. How do I make this work?

Another query, do under-relaxation factors only have an effect on convergence stability and computational time? Do they affect the final solution too?

Thanks!
