Warning: "zero diffusivity"
I have a heat & mass transfer problem (fuel cell).
When I initialize the calculation, the following warning comes up:

Warning: Mass_Diffusivity: invalid (zero) diffusivity.
Please check material properties.

I'm utilizing "Multicomponent" scheme in "Mass diffusivity" panel of the defined "Mixture" and set all Dij to 0.00005.

That means there is no "zero diffusivity" in the system.

So why should I get this warning?

Your reply is highly appreciated.
