Abstract

A novel method for particle generation is proposed based on ABAQUS. For the method, a script is constructed in programming language Python, and run by ABAQUS to generate particles. In the script, built-in functions of ABAQUS are firstly used to import geometry model, and then to search for its boundaries and partition the domain. A particle model is finally established by converting sub-domains obtained from partition into particles. The present method is available for arbitrary domains and produces particles with basically rectangular distribution. An example of particle generation for a half of ring is used to compare the approximation accuracy of particles by both the present and traditional methods. The case of a truncated-ogive-nose projectile is given to illustrate the ablity to establish parameterized particle model by combining the present method with the parameterized geometric modeling of ABAQUS. Finally, particles generated by the new method are employed to SPH calculation of high velocity impact, which demonstrates its feasibility in practical application.
