I am simulating a curing reaction of an epoxy resin. Momentum, heat and mass transfer have to be coupled and solve simultaneously.

For the momentum equation, I am solving a 2D, steady state, creeping flow, entering in a rectangular porous domain. I am basically solving equation of motion in 2D adding Darcy's law for porous media.

For the heat transfer equation, I am solving for one convective term (the domain is moving), conduction in one direction, and a heat source. This heat source comes from the epoxy itself that is undergoing an exothermal reaction.

For the mass transfer equation, I am solving for a convective term and the exothermal reaction. This reaction is of order n.

I have not been able to implement the n-order reaction and couple it with the heat source in the energy equation. As Rui suggested in 2010, CFX does not include a kamal type equation (see link below).

Does anyone know if the new version 14.5 has the possibility to include n-order reactions and couple it with a heat source?

Do I have to add a subroutine using FORTRAN?

I am new in CFX 14.5, so I want to make sure that my last resource is to program in FORTRAN since I do not have any experience with this language.
