Robust and scalable 3-D geo-electromagnetic modelling approach using the finite element method
Alexander Grayver,Markus Bürg +1 more
TL;DR: This paper considers the magnetotelluric case and verify the numerical scheme by using COMMEMI 3-D models and shows that for multiple right-hand sides the direct solver-based pre-conditioner can still be faster for problems of medium size.
