PRECONDITIONING OF VOXEL FEM ELLIPTIC SYSTEMS
TASK Quarterly, 2007 The presented comparative analysis concerns two iterative solvers for large-scale linear systems related to µFEM simulation of human bones. The considered scalar elliptic problems represent the strongly heterogeneous structure of real bone specimens ...

Recent developments on electron optics simulator
AIP AdvancesRecent developments on the electron optics simulator (EOS) are reported in this paper. The EOS is a finite element two-dimensional (2D) and three-dimensional (3D) electrostatic particle steady-state trajectory code that has been widely used for beam ...

Zhejiang Daxue xuebao. Lixue ban, 2010 提出了一种修正的代数多重网格解法,来求解具有对称二阶椭圆算子的变分不等式的有限元离散问题.该方法基于离散椭圆型变分不等方程的线性互补性,运用积极集策略,对Gauss-Sidel光滑迭代后的近似解进行一个后处理,以满足不等式约束,从而解决了标准代数多重网格法在求解自适应网格上的变分不等式时不收敛的问题.数值实验表明了该算法在一致网格和h-自适应网格上的计算有效性和健壮性.为了减少计算时间,根据该修正算法内在的并行度,提出了一个并行计算格式,数值结果给出了该并行的加速比和效率.
