Abstract
En 中文
• An adaptive quartic SPH kernel is developed using the Cox-de Boor algorithm. • An algorithm for finding the intermediate knot is designed so that the adaptive quartic SPH kernel can remove the tensile instability. • The effect of the intermediate knot of the adaptive quartic SPH kernel on the stability of the system is analyzed. • A three-dimensional liquid drops model is calculated.
