Which term would be used for simulating the human body's mechanical and biological aspects?

• A. Formal drawing techniques
• B. Data Modelling
• C. CAD
• D. Digital human

Answer: (D)

Simulating how the human body behaves biomechanically and biologically is described by a digital human. A digital human is a virtual representation that integrates anatomy, biomechanics, and physiology so engineers can test how postures, loads, and products interact with the body. It is the best fit because it denotes a full-body, dynamic model used for realistic simulation, not just a drawing or a data structure. Formal drawing techniques focus on creating visuals, not dynamic behavior. Data modelling deals with organizing information. CAD provides precise geometric models and drawings, but by itself it doesn’t inherently capture the biological or physiological aspects of how the body moves and responds.
