Dear experts,

Using Maxwell-Stefan equation for diffusion, I want to set anisotrpic values for the diffusion coefficients. This can be easily done if I use Fick's equation but it does not look straighforward if one uses Maxwell-Stefan. Any suggestions and ideas are highly appreciated.

Thanks

Hi Rabeb,

Yes, COMSOL can easily solve these equations. The module to use is Mathematics/PDE Interfaces and then choose one of the forms: coefficient/general/waek.

Hope this helps,
Mohammed
