摘要
针对半线性抛物混合初边值问题,给出了一种基于应力佳点的二次有限体积元格式,并证明了格式的收敛性.具体算例表明该格式计算效果良好.
A kind of quadratic finite volume element method based on optimal stress points is presented for semilinear parabolic equations with mixed initial boundary conditions.It is proved that the method is convergent.A numerical example illustrates the effectiveness of the scheme.
