is fluent capable in fixed beds simulation?

Recently, my boss asked me to simulate a reaction in fixed beds.
I've done some search, and found most models are upon a porous media basis, which to some extent do not agree with the reality. Does anyone know how?

Yes, you can simulate fixed bed with reactions with Fluent.
Porous bed which is one way to model fixed bed. There is another option which is multiphase modelling. You can choose Euler-granular Model (or other appropriate model) to simulate fixed bed. To incorporate reactions between phases you need to specify heterogeneous reaction through phase interaction panel by UDF. Well, Multiphase modelling is time consuming but worth to try.
