Question

For a convective boundary, the natural boundary condition is a balance of energy transfer across the boundary due to conduction and/or convection.

(a) True

(b) False

The question was posed to me at a job interview.

I want to ask this question from Single Variable Problems in chapter Single Variable Problems of Finite Element Method

Answer 1

Correct option is (a) True

Best explanation: The existence of convection heating or cooling leads to the convection boundary condition, known as Newton boundary condition. For a convective boundary, the natural boundary condition is a balance of energy transfer across the boundary due to conduction and/or convection.
