Why Use Engineering Simulation?

What is Simulation?

"imitation of reality"

In engineering this generally involves the use of known physical principles with the aim of improving design or configuration


Why Use Simulation?

Supplement physical testing:
  • Save Cost
  • Save Time
  • Visualise Concepts

Simulation Benefits

Save Cost
  • Physical Prototypes are expensive due to unique components, bespoke tooling and lack of economies of scale
  • Physical Testing Often involves expensive facilities
Save Time
  • Virtual Prototypes much quicker to create
  • Virtual Testing quicker to configure and in many cases can be faster than real time

Visualisations

Visualise
  • Stress Distributions
  • Fluid Flow
  • Utilise CAD geometry
Animate
  • Motion (Kinematics)
  • Deformations

Simulation Complexity

Hand Calculations
  • Fundamental Analysis
Parametric Models
  • Fast for evaluating coarse changes
Multi Body Systems
  • More complex interactions can be modelled
  • Combine different methods
Systems Engineering
  • Decompose into modular systems
Design of Experiments
  • Summarise complex systems into a simplified form
