Hello, ANSYS Maxwell is indeed suitable for modeling transient effects, including those at frequencies in the order of MHz. It uses finite element analysis (FEA) to solve transient problems, which would be relevant for your study on grounding systems subjected to lightning. Maxwell 3D or Maxwell 2D can be used for finite element analysis to extract parameters and plot field distributions, which may include transient effects due to lightning strikes.
