3. What is Simulation?
Simulation is the act of
representing some aspects of the
real world by numbers or symbols
which may be manipulated to
facilitate their study

4. What is a Process Simulator?
An Engineering Tool which performs,
* Automated calculations
* Material and/or energy balances
* Physical property estimations
* Design/rating calculations
* Process optimization
It is not a Process Engineer !
