amem (Adapted Meshes for Electromagnetic Modeling) is a python script that describes the steps to determine the parameters to be applied for the generation of adapted meshes for electromagnetic modeling.
Based on this approach, all element sizes are constrained by the global spacing dg. When refining the mesh at receivers positions and when embedding the sources, local spacing ds specifies the size of the mesh according to the distance to such regions. Furthermore, the outer boundaries are placed at least four skin-depth away from the modelling region of interest, so that electric fields generated in the centre of the computational domain are sufficiently attenuated by the artificial model boundaries, in accordance with the imposed Dirichlet boundary conditions.
Requests and contributions are welcome.
