Github Valple Spectral Element Method 1d Wave Equation The above solution is exactly the same presented for the classic finite element method. now we introduce appropriated basis functions and integration scheme to efficiently solve the system of matrices. The spectral element method is particularly useful for simulation problems where the free surface plays an important role, and or in which surface waves need to be accurately modelled.
Spectral Element Method For The Helmholtz Equation A spectral element method for the approximate solution of linear elastodynamic equations, set in a weak form, is shown to provide an efficient tool for simulating elastic wave.

Basic equations the numerical description of 1d elastic waves propagating in a heterogeneous media is a natural extension of the homogeneous case. from an algorithmic point of view, now we allow both mass, and stiffness matrices to be initialized separately for each element. In the finite element community, a method where the degree of the elements is very high or increases as the grid parameter h increases is sometimes called a spectral element method. Hapter 4 spectral element methods the spectral element method is a high order numerical method that allows us to solve the seismic wave equation. in 3d heterogeneous earth models. the method enables adaptation of the mesh to the irregular surface topography and to the vari. When a lot of transform between spectral coefficients and physcial values are involved, chebyshev method is a better choice, since fast transform is available. in other cases, legendre bases might be the better choices.
