Details of the abstract

Title of paper Speeding up the inversion of the 3D MT problem
List of authors Varilsuha, D
Affiliation(s) Istanbul Technical University
Summary In this study, I have investigated different algorithms that can greatly reduce the inversion time of a 3D Magnetotelluric problem. These algorithms include the right choice of the partial differential equations to solve an EM problem, a hybrid finite-difference and finite-elements numerical technique, employment of multiple GPUs for the calculations, the mesh decoupling technique, and other good implementation practices. When all of them are applied in conjunction, the inversion time for a medium-sized 3D problem can be completed in around an hour.
