We present a new approach for 2-D magnetotelluric forward numerical modelling in contrast to traditional methods like finite elements or differences. The method used solving the partial differential equations is based on mesh-free technique which does not need an underlaying mesh grid. use Meshless Local Petrov–Galerkin (MLPG) combination with radial basis functions simulate response of given conductivity model plane-wave source. compare solution known simulation programs and simple...

SUMMARY We present a new 2-D forward modelling and inversion scheme to interpret magnetotelluric/radio-magnetotelluric data by utilizing novel meshless operator. use this discretization technique within an inverse recover conductivity structures from given magnetotelluric data. To approximate solutions of the partial differential equations that describe experiment, we discretize subsurface only in terms nodes. These node sets, which are simple generate, used derive operators’ approximations...

We present a novel two-dimensional inversion scheme, which uses meshless approximation framework to recover Earth models from available magnetotelluric data. Given the theoretic description of forward modelling we provide an extension full algorithm using parts approximation. To validate newly developed example calculation including topography, where unknown conductivity structure with help measured apparent resistivities and phases.
