coupling multiphysics problem

Please login with a confirmed email address before reporting spam

Hello,

I am working on CFD simulation for neutralization reaction in a laminar flow regime. I used the following physics: laminar flow, Reaction engineering and transport of diluted species. However, this setting computed only the transport of the diluted species and didn't couple the result with the reaction engineering node to account for the reaction itself. The time dependent solver (BDF) converged only to a value around zero. In short, I would like to get your expertise to help me couple these physics properly to obtain the concentrations of the reacting species. I am using COMSOL 4.4 for your info.
