Table 4 Time and memory used in MoVFEM with the non-flat topography model

From: Multi-order vector finite element modeling of 3D magnetotelluric data including complex geometry and anisotropy

Element Lagrangian
Grid \(N_\text{e}\) \(26 \times 30 \times 40\)
DoF 773,152
NNZE 39,529,728
Assembly time 2070 s
Total time 1689 s
  1. Times are shown in seconds, and the memory is presented in terms of the number of elements \(N_\text{e}\), the number of unknowns (DoF) and the number of non-zero entries for the global array NNZE
