Description
My understanding is that Castro currently implements diffusion of temperature (i.e. a fluid with areas of hot and cold temperatures will evolve towards a uniform temperature eventually), but not yet diffusion of species concentration (i.e. a fluid with areas of high concentration in species 1 and 2 respectively will evolve towards a uniform concentration eventually).
I was wondering: are there plans to implement diffusion of species concentration in Castro?
If not, would you have pointers as to how to implement this in Castro, if I had to do it myself?

Research direction
Start with the linked Castro diffusion documentation and determine whether species-concentration diffusion is already supported alongside temperature diffusion. The issue provides no file, test, or implementation entry point; done would require a decided implementation path and a way to verify that species concentrations evolve toward uniformity.
