Sometimes your computer may display an error that an interface digital wave propagation analysis error is displayed. There can be many reasons for this problem.
The mathematical error associated with finite-difference wave propagation simulators in discontinuous advertising and marketing consists of twocomponents from. The first padding is a higher order error when diffusion over the network occurs; perhaps it can be controlled by a higher ordermethods. The second characteristic arises from the mismatch between digital equipment and physical interfaces. We offer amazing explicitEstimate the interface imbalance error per second to apply to each finite difference scheme at multiple temporal and spatial levels.to the acoustic wave equation. Our research, supported by numerical experiments, demonstrates what causes the interface errorin the last time shift of the first order, proportional to the distance, for example, between the interface and computing means. The 2D experiment showsthat the screen error during higher order methods cannot be eliminated, assuming 1D our own analysis yieldsgood forecaston the general behavior of the numerical solution in higher dimensions.

… Despite the significant development of high-order finite difference schemes over the past few decades, this method is only a first-order fact when it comes to reproducing sharp internal material. parameter breaks when using only averaging methods (Gustafsson and Wahlund, 2004; Symes and Vdovina, 2009). Alternatively, a finite difference method can be considered second-order accurate in terms of implementing interfaces if the average of the type parameters, kindly provided by Moczo et al. (2002) previously belonged to Et (Vishnevsky et al. 2014). …
… The transition between water and progress in fully elastic modeling is an additional challenge in conedge-to-edge modeling (De Basabe and 2015); As reported by Gustafsson and Wahlund (2004), Symes and Vdovina (2009) and Vishnevsky et al. (2014), however, noted that it is not easy to achieve high accuracy in acoustic-acoustic joints with sharp discontinuities in material parameters. It seems reasonable to tackle the acoustic-acoustic problem first, before moving on to the more difficult elastic-elastic critique or the even more problematic acoustic-elastic problem. …
… Transition between water and reservoir in fully adaptive simulation is another finite difference problem (From Simulations Basabe and Sen, 2015); however, as reported by Gustafsson and Wahlund (2004), Symes and Vdovina (2009) and Vishnevsky et al. (2014), it is indeed nontrivial to achieve high accuracy at acoustoacoustic boundaries, when discontinuities in material parameters can be pronounced. It seems useful to help you solve an acoustic-acoustic problem before solving a much more difficult elastic-elastic problem, and sometimes even a more difficult acoustic-elastic problem. …
Implement proper inner endingsIt is difficult to make differences in sentences with high spatial accuracy. Propagation of fields in a locally very homogeneous part of a set can be achieved with spectral accuracy. In most cases, implementation interfaces are considered accurate at best on a small scale. This situation can be exacerbated by appropriately limiting the range of this modeling network. Interfaces can be built anywhere on the network, but this detailed information about the location of the interface must be correctly printed in this rough network simulation. This can be done by starting with each representation of a sharp hardware jump in the wavenumber domain and limiting the highest wavenumber to some maximum wavenumber allowed for the simulated power system. The resulting wavenumber representation is converted to the spatial domain. An alternative method is to create a fine mesh model that can be low-pass filtered to remove wave numbers, in particular the maximum wave number allowed forcoarse modeling mesh. Then the fine grid must be digitized with the necessary harmonics for the coarse grid to be modeled. An accurate and flexible implementation interface is certainly a prerequisite for reducing step diffraction in multidimensional finite difference simulations. The proposed strategy achieves this. The content of the initiating event should be limited to the level at which the main spatial sampling is approximately 4.5 grating points per the shortest wavelength. The simulation results show that the use of the interface is accurate and provides at least sixth order for large contrasts. The proposed procedure can be used for all systems of incomplete differential equations that can be formally expressed in terms of a material parameter using the equal sign. For geophysical modeling, the most important cases may be the Maxwell equations and the equations for acoustic and elastic waves.
… The two-layer averaged model and its solution is an amazing case study for studying all the error components in numerical methods, see Symes Vdovina and (2009)< /brand>. I could use the same example to later express the error components in DG tactics and suggest suppression approaches as a path to interface error. …
