About lightning spike generation

AI Thread Summary
The discussion focuses on generating lightning signals in COMSOL Multiphysics for a master's project related to grounding analysis. The user seeks guidance on modeling lightning effects and applying them to grounding rods. Participants inquire about the user's current work, including the source voltage and impedance models being considered. They also mention relevant industry standards, such as EN-61000-4-5, for immunity testing. The user expresses difficulty in implementing these lightning spikes in COMSOL.

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
 
Thread 'Weird near-field phenomenon I get in my EM simulation'

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
