Charge density estimation for the finite sized isolated structures using finite element method
[attachment=64894]
Motivation
ESD ½*C*V2 abrupt release of charge from one object to another
Orbiting Satellites
Loss of information
Hardware damage
Permanent satellite damage
Continue
No closed form of expressions
capacitance = main parameter
Capacitance will be estimated for different geometry of satellite
we can save several expensive satellite component by reducing the probability of ESD
Example
the physical systems stabilizes at the minimum level of energy.
The general equation of energy in an electric field
Is

Discretization of the Domain
Generate an equation for each element and approximate it with the help of a shape function
