Hi,

I am trying to simulate fluid flow in a 3-D pipe. I would like to add Isotropic diffusion into my simulation.

I am not able to find out how this can be done in COMSOL 4.1.

If anyone has a tutorial which illustrates how artificial diffusion can be adopted, please let me know.
or
If you can explain me how the diffusion can be added, it would be much aapreciated.

Regards
Nash

You have to enable the extended view of the comsol interface, then you will see an option probably.
