jr33 is on a distinguished road
Currently I can solve scalarTansport ( advection-diffusion) problem in openFoam using simpleFoam. Diffusion term is scalar and constant in current case.

is it possible to add radial diffusion term to scalar diffusion variable (DT)?

can I define scalar diffusion term as scalar diffusion tensor?

Thanks
jay
