Question

In Finite Element Methods (FEM), a boundary value problem is a set of differential equations with a solution, which also satisfies some additional constraints, known as ___

(a) boundary conditions

(b) nodal values

(c) equilibrium equations

(d) energy minimum

I had been asked this question during an online exam.

I'm obligated to ask this question of Boundary Value Problems topic in portion Single Variable Problems of Finite Element Method

Answer 1

Correct choice is (a) boundary conditions

To explain I would say: A boundary value problem is a set of differential equation with a solution, which also satisfies some additional constraints, called the boundary conditions. Nodal Values are the values of a variable at each node obtained as a result of finite element analysis. Equilibrium equations are used in free body diagrams.
