UDS diffusivity
 

Hi there,

I am solving one UDS in different zones(fliud and solid zone),

now the diffusion coefficients are different in two zones.

I want to kown is it possible to specify two diffusivities for one UDS in different domain?And what should I do to specify?

thanks a lot!

Hi there,

I am solving one UDS in two different speices (air+water),

now the diffusion coefficients of UDS is different in two species.

The diffusion coefficient of UDS in Air egale: Dair=1.1 e-5

The diffusion coefficient of UDS in water egale Dwater=1.2 e-9

I want to kown is it possible to specify two diffusivities for one UDS in different species ?And what should I do to specify?

thanks a lot!
