      The Diffusion coefficient of the SOFC module, use the default of the diffusion coefficient of FLUENT, it is calculated by the following equation: Dij,eff = (ε/τ) Dij Where Dij is the default diffusion coefficient of Fluent, ε is the porosity, τ is the bent rate. Note: Even when the SOFC module is used without the diffusion coefficient, kinetic theory and unique it is also possible to use a UDF.
