What does simulating mean?
Simulating means imitating something or representing a real situation through a model. The word is especially common in science, engineering, computing, medicine, education, and training, where conditions can be recreated safely before a procedure, experiment, or decision is attempted. For example, engineers may simulate earthquakes to examine how a structure responds, while a medical trainee may simulate the symptoms of a disease for practice. Simulating can also mean merely behaving or appearing like someone or something, as when a comedian simulates a familiar voice, although this older sense often carries the implication of a recognizable imitation. In modern technical use, the word is closely associated with computer models and virtual environments, but it is not limited to digital simulations. Its usefulness lies in allowing people to study outcomes, train participants, or test possibilities without immediately confronting every danger, expense, or practical difficulty of the original situation.
verbTo imitate the appearance, behavior, conditions, or process of something. In technical and scientific contexts, it can also mean to represent or analyze a system using a mathematical or computational model.
- To imitate the appearance, actions, or characteristic features of someone or something.
- To represent real conditions or processes through a model, experiment, or computer program for study or prediction.
"The engineers simulated extreme weather conditions to test the bridge's structural integrity."
"The actor spent weeks simulating the fatigue of a soldier on a long march."
"The software simulates traffic patterns before changes are introduced to the road network."
A simulation can explore thousands of possible outcomes without exposing the real world—or its people—to the risk.

Where does simulating come from?
The word derives from Latin simulare, meaning “to copy” or “to imitate,” from simulus, meaning “like” or “similar.” English borrowed the verb in the 17th century, initially with senses concerned with imitation and representation. Its later scientific meaning developed as methods for modeling real systems became more precise. Latin simulacrum, meaning “image” or “likeness,” and the English words simulation and simulator share this ancestry, as does simultaneous through the Latin root simul, meaning “at the same time.”

How simulating is actually used
The word is common in technical, scientific, academic, and training contexts. In ordinary use, it can imply that an imitation is imperfect or merely apparent, though this connotation is not always intended.
Easily confused with simulating
To simulate is to imitate or model something, whereas to stimulate is to encourage activity, growth, or response.
