Dear All participant of this forum
I am simulating a planar couette flow in LBM. The study is on the shear banding of colloidal glass. I have osmotic pressure
as a driving force and i have multiplied it with a prefactor to make it in the LBM unit.
I read from a book that LBM by itself has ideal pressure (i.e rho*cs_2) in it and one has to subtract this term from the applied pressure during implementation. In my simulation i had subtracted this term but i found it is so big and keep on increasing the density in my simulation.
Is there any one here who has experience in simulating non ideal fluid?
