Physics based modeling and simulation
"... physics based modeling for engineering analysis, trade studies, requirements definition, and simulation in applied physics, optics, engineering, energy ..."
What is a physics based model or simulation?
- define the system
- what do I already know about the system?
- what do I want to know about the system?
- what level of fidelity do I need?
- understand the physics governing the system
- what observations and data do I already have?
- what laws of physics (first principles) affect the system?
- are there simplifying assumptions? when are they valid?
- develop mathematical algorithms describing the physics
- write computer model for the system
What is a physics based model or simulation used for?
- used to describe interaction of complex systems
- show feasibility of a concept
- make predictions of system performance
- flow of requirements (up or down)
- conduct trade studies between competing systems or components
