boundary spring

基本解释

But the energies of the two systems are not equal, and the difference is the complementary energy adsorbed by the boundary of the spring.
但是两个系统的平衡状态的能量不同，其差值为弹簧支撑边界所吸收为系统的余能。
The special problems with the complicated shell structure are dealt with by using the master-slave technique, penalty element and boundary spring element.
采用主从节点技术、罚单元和边界弹簧单元处理了复杂壳体结构的特有问题；
By boundary attraction the mesh boundary approached the domain boundary and inner-domain boundary, the spring and equilateral tetrahedron approach method optimized the mesh structure effectually.
其中，边界引力有效解决了流场边界恢复和内嵌边界问题，弹簧振子和正四面体趋进技术有效调整网格结构并提高网格质量。
