how can we control fluid initializations?

[jh-chung1]

Thank you for the useful code. I want to customize the fluid initializations for a given porous medium to run a multicomponent Shan-Chen LBM.

My questions are: 1) What is the current approach to initiate fluid phases? 2) How can I customize it?

Thanks.
