simulate
To replicate or imitate the physical behavior of a system, material, or environment using a digital model and mathematical algorithms.
Simulating involves testing how a design will react to real-world forces like gravity, wind, heat, or stress without building a physical model.
Word relationships
- replicate: Replicate means to copy or duplicate exactly, while simulate means to mimic the behavior of a system under specific conditions.
- model: Model can refer to creating the static shape, whereas simulate specifically implies dynamic testing over time.
- physical test: Testing a real, physical object in a physical environment (e.g., a real wind tunnel).
Commonly confused with
- stimulate: Stimulate means to encourage activity or growth, while simulate means to mimic or model physical behavior.
Word family
- simulation (noun): The digital replication of a physical system's behavior.
- simulator (noun): A machine or program designed to provide a realistic imitation of controls and conditions.
Collocations
- simulate conditions
- simulate stress
- computer simulation
- flight simulator
Example sentences
- "We can simulate the aerodynamic drag and structural stress on the bridge during a major hurricane." A structural engineering report on a new suspension bridge.
Memory hook
Think of 'similar'. When you 'simulate' a car crash on a computer, you are creating a digital event that is highly 'similar' to a real crash. Simulate makes it similar to reality.
When not to use
Do not use when you are simply animating a model for visual effect without calculating physical forces or scientific data.
Fun facts
- Some of the earliest complex computer simulations were run during the Manhattan Project to predict the behavior of nuclear detonations.
