Engineering mathematical models are idealized descriptions of physical systems, including geometry, material behavior, loads, boundary conditions, constraints, and the governing equations selected for analysis.
How It Works
The analyst chooses a model that is simple enough to solve and rich enough to answer the engineering question. A finite element solution then approximates that selected model. If the model is poorly chosen, a numerically accurate result can still be physically misleading.
Why It Matters
The source positions finite element analysis as part of an iterative engineering process: define the model, solve it, assess the result, compare against expected physical behavior, and refine the model when needed.
