WebDENISE-SH 2D time-domain isotropic (visco)elastic finite-difference modeling and full waveform inversion (FWI) code for SH-waves, which I developed together with Denise De Nil and Eva Dokter. A manual for the SH code is not available, but most features are similar to the P-SV code DENISE-Black-Edition, for which a manual is available at: WebFWI.jl. A Julia package for solving the Full Waveform Inversion on a regular rectangular mesh. For forward modelling and sensitivities it uses either a direct solver or a block Shifted Laplacian Multigrid preconditioner with BiCGSTAB. Webcnn-fwi CNN-EFWI is a repository for full waveform inversion at the framework of PyTorch. You can use it to perform acoustic or elastic forward modelling and backpropagation in 2D or 3D case, it can simulate wave propagation to generate seismic synthetic data, invert for the acoustic/elastic parameters of undergrond. crown point indiana bmv hours
