In order to reconstruct initial flow field for particle methods based simulations for realistic complex engineering problems, this paper presents a isosurface extraction preprocessing tool for complex geometric 3D flow field using particle based methods such as smoothed particle hydrodynamics (SPH). It can reconstruct the boundary and fluid particles for flow field of SPH simulation. The initial boundary particle information is obtained from marching cubes covering the whole surface, meanwhile taking advantage of its mesh we achieve filling the uniformly distributed of internal fluid particles. Furthermore, to ensure the stability and accuracy of SPH, we propose a moving iterative algorithm based on the particle systems, which achieves a uniform distribution of boundary particles and calculates their normal vectors. The tool employs volume data and standard CAD files, such as STL model, as the original input of algorithm. The efficiency and robustness of our new particle method preprocessing tool has been verified by various examples.
