谱元法 SEM(spectral element method)基于弹性力学方程弱形式基础之上,在有限单元上进行谱展开,从而使该方法具备了有限元适应任意复杂介质模型的韧性和伪谱法的精度,该方法又被称为高阶有限元方法或伪谱法的域分解 谱元法(SEM),最初是Patera在1984年计算流体力学中提出. 它在有限元上进行谱展开,所以具有有限元方法...
1. The spectral element method based on streamline upwind Petrov-Galerkin(SUPG)stabilization scheme was developed to solve multidimensional radiative heat transfer in semi-transparent media. 本文发展了基于流向迎风彼得罗夫-伽辽金(SUPG)格式的谱元法来求解多维半透明介质内的辐射传递。
The electromagnetic fields in a fast-rotating ferromagnetic cylinder are computed using a spectral-element method, considering the heavy saturation of the surface. The method offers a far better convergence of the discretisation error compared to the finite-element method. Upwind techniques for ...

The method combines the flexibility of a finite element method with the accuracy of a spectral method. One uses a weak formulation of the equations of motion, which are solved on a mesh of hexahedral elements that is adapted to the free surface and to the main internal discontinuities of the...
The propagation of seismic waves through Earth can now be modeled accurately with the recently developed spectral-element method. This method takes into account heterogeneity in Earth models, such as three-dimensional variations of seismic wave velocity, density, and crustal thickness. The method is ...
