Simulate the lightning strike on a drone

Hello I have a drone model and I want to measure the electric field that is occurring from the lightning strikes on it. The lightning is represented by a standard impulse voltage 1.2/50us. I used the analytic function to represent the shape of this impulse. But how can I inject this equation through the drone?

You can use the function to define a boundary condition on the drone. This will look different depending on the application module you are using.

Thank you for your response. when I run the program it gives me an undefined variable (V) error I don't know where is the problem. And I am using electric currents physics can you tell me please what is the appropriate boundary condition?

Sounds like you have domains with zero conductivity while ec needs a small conductivity also in insulators such as air. I guess you would apply a potential BC to the drone, no?

I used the terminal boundary condition then I defined the impulse voltage equation without errors. Unfortunately, the electric field is zero everywhere.
