Discontinuous Galerkin Time Domain Methods for Acoustics and Comparison with Finite Difference Time Domain Methods
This thesis describes an implementation of the discontinuous Galerkin finite element time domain (DGTD) method on unstructured meshes to solve acoustic wave equations in discontinuous media. In oil industry people use finite difference time domain (FDTD) methods to compute solutions of time domain wave equations and simulate seismic surveys, the first step to explore oil and gas in the earth’s ...
متن کاملHigh-Order Numerical Methods for Maxwell's Equations on Unstructured Meshes
For more than fifteen years, spectral finite elements (i.e. finite element methods on hexahedral meshes with mass-lumping) showed their efficiency to model the propagation of acoustic and elastic waves in the time domain, in particular in terms of accuracy. Moreover, their mixed formulation [1] dramatically increases their efficiency in terms of storage and computational time. This approach, wh...
متن کاملAn efficient finite difference time domain algorithm for band structure calculations of Phononic crystal
In this paper, a new algorithm for studying elastic wave propagation in the phononic crystals is presented. At first, the displacement-based forms of elastic wave equations are derived and then the forms are discretized using finite difference method. So the new algorithm is called the displacement-based finite difference time domain (DBFDTD). Three numerical examples are computed with this met...

Time-dependent wave fields are often approximated using wave equations. Due to the oscillatory nature of wave phenomena, numerical approximations of wave equations are challenging. Approximating wave problems with tolerable accuracy requires the use of a relatively dense spatial discretization. For standard numerical techniques, such as the low-order finite difference and finite element methods...
