Hi Foamers ,

I have a question about uniform diffusivity . I am using fvMotionSolver class for moving the grid . I want to know that what is the function that uniform diffusivity use for diffusivity coefficient in the laplace equation ?

I appreciate any help from you.
Thanks and best regards.
Sasan.

upon closer inspection it just uses 1.0 (no surprise there) for a 'uniform' laplacian diffusivity.
