In this work we present an efficient and practical finite element 3D implementation, applicable to both airborne and ground-based TEM, developed with an octree-based hexahedral meshing that implements topography through a mesh deformation. This new implementation is compared to both 1D modelling and 3D finite-element tetrahedral modelling, in terms of accuracy, speed and memory requirement and inversion results on synthetic modelling. Furthermore, a verification of the topography implementation obtained comparing results with and without deformation is presented. Overall, the octree-based implementation is ~5x faster than tetrahedral simulation, while the memory cost in the forward modelling process is ~6x smaller.",
