Its simple you just know the properties of the new materials which you want to create and go over the fluent material database and click over to add up new materials and provide all the details and use this materials during define the particular portion of your domain. In FLUENT, you can define six types of materials: fluids, solids, mixtures, combusting -particles, droplet-particles, and inert-particles. Physical properties of fluids and solids are associated with named materials. These materials are then assigned as boundary conditions for zones.

When you model species transport, define a mixture material, consisting of the various species involved in the problem. Properties will be defined for the mixture, as well as for the constituent species, which are fluid materials.

For an example :-

Good Luck

Thank you very much its very helpful

Most Welcome !

anyone know how to add the properties of the materials as a function of temperature in Fluent

Thanks

Very informative reply. 

Kindly post how to add new materials in CFX.

Thank you.

I'm working on Copper Electro-refining. Anode (Impure copper), Cathode (Steel), Electrolyte as Aqueous solution of H2SO4 + CuSO4. Model using: Energy; Turbulence (k-e); Potential Model, Species Transport Model.

i) How do I create a new solid material (for Anode) having composition lets say 96% Cu rest are Zn, silver, gold, Al etc etc? I think I need to create user defined data base, properties can be found from literature but how to specify the composition of that solid material?

ii) How do I add/define SO4-2 ions in my fluid domain?

Please help.
