Abstract

It is demonstrated that interelectrode capacitances can be obtained for three-dimensional electric-field geometries from the Z-matrix finite element formulation. The FORTRAN program WFEMZ has demonstrated that relatively large problems can be solved in reasonable time without overburdening available computer assets. It is shown that reusing suitable pass 1 results can save a substantial amount of computing time. Numerical accuracy of the method, though dependent upon the grid resolution selected by the user, is quite acceptable for reasonable grid spacings.<>

电极电容从一个z矩阵有限元公式
证明了用z矩阵有限元公式可以得到三维电场几何的电极间电容。FORTRAN程序WFEMZ已经证明,相对较大的问题可以在合理的时间内解决,而不会使可用的计算机资产负担过重。结果表明,重用合适的pass 1结果可以节省大量的计算时间。该方法的数值精度虽然取决于用户选择的网格分辨率,但在合理的网格间距下是完全可以接受的
