Question

Which of the following statements is true about Finite Element Analysis (FEA)?

• A. Residue obtained equals zero
• B. The solution is exact.
• C. The solution is exact at the boundaries.
• D. It is an analytical technique.

Hint:

When using FEA, pay special attention to defining boundary conditions accurately, as the correctness of the solution heavily depends on these settings.

Answer 1

The Correct Option is C

Finite Element Analysis (FEA) is a numerical method, not an analytical one, and generally does not yield zero residue nor an exact solution throughout the domain. However, it can provide exact solutions at the boundaries, particularly when boundary conditions are strictly defined, as FEA is designed to approximate the solution well within these constraints.
