FOGs in sewer system
(OP)
I am working on a CFD model and am having a hard time finding the properties to input them into ANSYS or solidworks. In particularly dynamic viscosity. An help to point me in the right direction would help. Thanks.

FOG are a mixture of stuff (as the name implies), anything from an oily scum layer to large chunks of fat floating by to suspended fats (if surface tension is low). Any number for viscosity should be taken with large amounts of salt since it may not apply to whatever you try to model.
I've never seen viscolisty data for FOG, you should find some for some pure species but if that is helpful ... see above. (Glycerine wikipedia, most technical greases their datasheet)
One note: Viscosity of typical biogas slurries went anywhere between 1000 and 10000 mPas (and surely higher but not in the plants we had measurements taken), I'd expect this variety within FOGs too.
If you describe the application you want to model, maybe someone here can give you more ideas where to find data.
