Description

The lattice Boltzmann method (LBM) has become an alternative to the conventional computational fluid dynamics methods for solving Navier-Stokes equations. Unlike traditional numerical methods which solve for the macroscopic variables, such as velocity and density. The LBM is based on the microscopic kinetic equation for the particle distribution function. The macroscopic quantities are obtained through moment integration of the distribution function.

In CFD/LCS, we have developed an in house LBM code package derived from previous internal research efforts. The LBM_D2Q9 Fortan code, a simple implementation of the lattice BGK scheme, is one part of the package which is used to solve fluid-structure interaction problem. Please refer to the user guide for detailed information.
