I had a similar problem. But it was to generate a model that would include Zn ion and the Co Crystalized ligand.
So I had to modify the scripts I was using. and I succeeded in transferring the both the ligand and the cofactor.
If your problem is in this same line, then you might have to work on the script.

Dear Fadhila,

As an alternative, you could also try modeling your protein with Structuropedia @ http://structuropedia.org.

In your amino acid sequence to be modeled, simply place an X where the FAD ought to be.

You can also email me the amino acid sequence that you wish to model--and I would be glad to feed it into Structuropedia at my end.

With warmest regards,

Dear All,

I wanted to make a model of human flavin-containing monooxydase 3 (FMO3) enzyme from the template FMO of Saccharomyces pombe. This enzyme has FAD residue that is important to the project I'm working on. But of all the model output, none came with this FAD residue.

I have tried simple usage automodelling provided in the manual and modelling with the guide from basic modelling tutorial (provided here: https://salilab.org/modeller/tutorial/basic.html). Lastly, I also have tried to use the script for including water molecules, HETATM residues, and hydrogen atoms to the model (described in here: https://salilab.org/modeller/manual/node18.html). The FAD residue was not present and I ran out of ideas on how to make this work. The FAD binding site is highly conserved in FMOs across species, so I don't see why it was excluded from the model. 

In the last try the script gave me this:

read_pd_459W> Residue type  FAD not recognized. 'automodel' model building
              will treat this residue as a rigid body.
              To use real parameters, add the residue type to ${LIB}/restyp.lib,
              its topology to ${LIB}/top_*.lib, and suitable forcefield
              parameters to ${LIB}/par.lib.

What should I do?
Your inputs are so much wanted and appreciated
