I have a choice of two options, analysing and implementing Lattice Boltzmann methods or traditional Navier Stokes based methods. I'm a CFD newbie and I have a rough idea (though not rigorous enough to produce a code) from my fluid mechanics classes about Finite Volume, Finite Element and Finite Difference methods. I am not clear about what would be a good starting point for this. There is already a question slightly similar to this : Is lattice Boltzmann suitable for simulation of incompressible Stokes flow? Can anyone comment on:
- Whether I need to become comfortable with traditional Navier Stokes based methods to understand and appreciate Lattice Boltzmann Methods?
- This question is based on the choice : What are the key pros and cons of NS-based methods vs LBM methods as far as code, efficiency etc. are concerned?
