About lightning spike generation

[AbdulManan]

Hello i am new user of in this forum...
i am working on COMSOL Multiphysics for my master project
i am working in the area of grounding so i have to analyze the material with lightning effect so i want to know how i can generate the lightning signal in COMSOL and how we apply to grounding rod

Welcome to the PF. What can you show us of your work and research so far? What models are you considering using for the source voltage and source impedance for the lightning source? There are also some lightning strike standard test procedures that are used in the industry for immunity testing, like EN-61000-4-5. Are you familiar with that test standard?

Recently i see these standards but i stucked these types of spike in COMSOL Multipyscis and also how i apply to the grounding rod
