Abstract
Lattice Boltzmann Models (LBM) are widely used to solve fluid mechanical problems in engineering and biomedical applications. First a brief introduction of LBM is given and an example model with three spatial dimensions is introduced. The model is relevant for blood flow simulation because it uses Reynolds and
Womersley numbers found in hemodynamics with a realistic time dependent pressure gradient as a boundary condition. A big advantage of LBM is the possibility of easy parallelization. Therefore different approaches
of implementations are discussed. To test parallelization, the example model is used as a benchmark. The simulation times are compared calculating the problem in parallel on one to four processors
