The conventional mesh-based CFD uses the Eulerian technique, thereby dividing a simulation space into a random mesh to calculate an approximate solution of Navier-Stokes equations in each discrete cell. It takes strenuous efforts to create a highly reliable mesh with which to accurately model the geometry of the structure and the flow region of interest. Moreover, since conventional CFDs analyze steady-state flows, there may be limitations in analyzing the physics of unusual flows.
The Lattice Boltzmann Method (LBM), which has recently gained recognition in the CFD industry, calculates probability distribution for particle velocity. It can predict time-varying values with NFLOW LBM ensuring very simple pre-processing compared to Navier-Stokes Equations-based CFD solutions. LBM is a new solution that transcends the limitations of current CFD solutions. It is extremely efficient in computation, especially when combined with NFLOW based on GPU parallel computing techniques.
