Ab initio refers to analyzing a system from fundamental physical laws. In mechanical engineering, it means running stress or combustion simulations based on basic quantum physics, rather than empirical test data. This approach is used when designing advanced alloys or studying fuel combustion behavior at a molecular level.
Mechanic Glossary
Ab Initio
A Latin term meaning "from the beginning," used in engineering and physics to describe calculations based on first principles without assumptions.
Frequently Asked Questions
It refers to building models or calculations based on basic physical laws (first principles) rather than using empirical test data or approximations.
It requires immense computing power because it calculates the interactions of atoms and molecules directly.
In materials science to design new engine alloys, or in combustion research to study how fuels break down.
