Mesh Generation for Ellipse Particles of Composite Solid Propellant

Abstract:

For analyzing the effect of different particles composing and distributing on composite propellant, it is necessary to generate mesh for the elliptical particles in composite propellant. A mesh automatic generation method is designed for the elliptical particles. This method is according to force-equilibrium mesh generation algorithm. And distance function and mesh size function is designed for the method. The program is in Matlab. The result shows that the method can automatically generate mesh and the mesh quality is good.
