Individual Physics you Learned in School

Heat in a rod, … Stress in a wrench S i h

• Individual equation sets … Applied to simple, (and sometimes not-so-simple) single-physics problems

In Reality – Multiple Sets of Physics Interact

• Typically bi-directional nonlinear coupling between multiple physical processes

Multiphysics: Multiple Interacting Phenomena
Could be simple: • Heat • Convected by Flow Could be complex: • Flow
– Navier-Stokes in tubes – Porous flow in plug
B

• Mass Transport
– Three chemicals: A,B,C – Reacting: A+2B → C

• Heat Transfer
– Exothermic reaction – Reaction rate temperature dependant

COMSOL Multiphysics Solves These!
• Multiphysics – Everything can link to everything. • Flexible – You can model just about anything. • Usable – You can keep your sanity doing it. • Extensible – If its not specifically there…add it! Trusted by 80,000+ Users Worldwide

Anywhere you can type a number … you can type an equation
• Or an interpolation function … • And it can depend on anything known in your problem • Example: Concentration-dependant
