Hi
I want to implement conductivity (K) of a material which is different in each coordinate direction.

Solver : laplacianFoam

K_x= 12 x
K_y = 1. 5+0.3y
K_z = 6z

Any idea?

Thanks in advance

should i write special matrices?

If you are referring to the hydraulic conductivity, I guess you must implement anisotropy via a conductivity tensor. However I do not quite understand why your conductivity approach is distance dependent in each component.

Hi Tom
Thanks for your kind reply.

Yes i am referring to a nano fluid which has position dependent conductivity as i mentioned its relation.

1.How to implement anisotropy tensor with position dependent components OR fixed components?

Any reference is welcome!
thanks for your time.
