# WaveSimulation_Matlab **Author:** zhaoqingwei **Date:** April 24, 2023 **email:** [zhaoqwei001@163.com](zhaoqwei001@163.com) ## SIMPLE SIMPLE SIMPLE!!! ## Main Purpose: I majored in geophysics with a direction in seismic exploration. Wave Simulation is the key to professional entry, so summarize your own code and share it with you. So the codes is just **simple** **simple** **simple**! The kernel code is just a few lines. Industrialization code, I recommend C, CUDA, MPI. #### Kernel Code: - 2D acoustic wave (three lines) ```matlab const1=v.*v*DT*DT/DH/DH; UU=imfilter(u2,dd); u3=2*u2-u1+const1.*UU+s(k)*f; ``` ## Keyword * **simple** **simple** **simple**! * 2-dimension; 3-dimension * acoustic wave;elastic wave;surface wave * sponge absorbing boundary condition;Split Perfectly Matched Layer;Convolutional Perfectly Matched Layer * isotropy,anisotropy media (VTI, HTI) * Finite Different Modeling * 简洁；简洁；简洁。2维；3维。声波；弹性波；面波；吸收边界；分裂pml；卷积pml。各向同性；各向异性（VTI，HTI）。有限差分模型。 ## Notes 3-dimension program cost memory num\*nz\*nx\*ny\*8/1024/1024(MB).Care about memory。 while nz=nx=ny=200,num=10; cost memory:610MB. while nz=nx=ny=600,num=50; cost memory:80GB. ## Thinks RToax [https://github.com/Rtoax](https://github.com/Rtoax) Guiting-geo [https://github.com/Guiting-geo](https://github.com/Guiting-geo) [Madagascar](https://reproducibility.org) [seismic unix (SU)](https://github.com/JohnWStockwellJr/SeisUnix) [CREWES](https://www.crewes.org/) ## Imag - 2D acoustic wave  - 2D elastic wave   - 3D acoustic wave
