This study compares the efficiency of 3-D transient electromagnetic forward modeling schemes on the multi-resolution grid for various modeling scenarios. We developed time-domain finite-difference modeling based on the explicit scheme earlier. In this work. we additionally implement 3-D transient electromagnetic forward modeling using the backward Euler implicit scheme. https://www.diegojavierfares.com/best-price-Electro-Mech-LX174-Ten-Inning-Baseball-Scoreboards-special-buy/
