Schemes in generalized finite differences for seismic wave propagation in Kelvin-Voight viscoelastic media

Seismic wave propagation in homogeneous and isotropic Kelvin-Voight viscoelastic media is dealt with the meshless generalized finite difference method. The schemes in generalized finite differences for the decoupled system P-SV and SH are obtained. For each scheme, a stability limit is achieved and the star dispersion is calculated. Some cases are shown using irregular discretizations.
