Isogeometric analysis method for electrostatic field problems
摘要
Abstract
In isogeometric analysis(IGA),a lately novel numerical technique,identical model is shared for geometric design and numerical simulation,which avoids the redundant procedure of remodeling simulation model in traditional methods and eliminates the geometric approximation errors during the mesh discretization.IGA is expanded to electrostatic field problems.The variables are constructed by the discretized control variables within the geometrically isoparametric concept.Using weighted residual approach the governing equations are weakened to the algebraic equations for the discretized control variables.For compulsory boundaries,they are given by the method of dividing groups.Numerical example of electrostatic field problems in a rectangular domain is carried out,and it is shown that the present method yields more excellent computational results,less amount of DOFs,quicker convergence than traditional one.Then,the characteristic impedance of elliptical stripline is calculated by the present method.关键词
