摘要
在基于直接边界元素法的层次式 h-自适应计算中 ,改进了层次式边界元的自动加密方法 ,提高了计算可靠性 .同时 ,将基于超收敛恢复技术的误差指示器实现于在常数元基础上叠加层次锥函数的寄生电容自适应计算 ,提出一种在不同阶次边界元上使用恢复技术的方法 .与同类软件相比 ,计算稳定 。
The auto-refinement scheme of the boundary elem en ts in the hierarchical h-adaptive computation is enhanced to improve the reliab ility.In addition,the superconvergent recovery technology is employed in the 3- D parasitic capacitance adaptive computation where the hierarchical cone functio ns is added into the constant boundary elements.A method using the recovery tech nology in the regions with different orders elements is presented.Compared with other similar software,this adaptive computation is faster-speed and more stab le.
