wonderful

I am doing a project using Shan and Chen pseudopotential method. I did not use anything to capture the interface separately. But using this method also interface evolves. Can you explain how this happens?

[@mariaakif4022]

can you explain bounce back boundary conditions of lbm?

[@PES2011vsFifa11]

What advantage does the LB method provide over using Finite Volume method on the original set of equations? Because the FV method can deal with the fluxes directly, instead of a requirement of distribution functions, etc.

LBM is more near towards random molecular nature of matter as compared to FVM. Efficient information flow one can achieve in LBM than FVM. Complex interfacial structure is easy to predict in LBM than FVM.

Karthik Ganeshan in LBM, one solves the boltzmann equation depending on the various parameters and use a relaxation time to reach equilibrium. NSE are a special case derived from boltzmann equation mostly using Chapman enskog expansion. So basically you are solving a flow problem starting from transient state itself rather than solving on equilibrium state only. While in FVM, FEM, FDM, SPECTRAL methods or other traditional methods which focus to solve NSE. What actually is being solved is approximate algebraic equation derived from PDE(NSE). Essentially algebraic equations are being solved. Conclusively, what actually you are solving is far different than what actual NSE represents leave aside Boltzmann's​ equation. I hope you can understand what advantages or efficient, accurate solution will be.

Can someone provide me full problem with solution procedure for lid Driven cavity.

[@muhammadusman7502]

Hello, Kindly can you provide full solved problem using LBM.

[@HighlandersUK]

But some of us do not work on linux.

[@Ransiwal]

Some programming step how it will be implemented

[@JimmyXC234]

That is the toughest part, therefore nobody will tell you.
