Question

In which of these methods, the calculation for interior nodes is done at the post-processing stage?

(a) Spectral element method

(b) Boundary element method

(c) Finite Element method

(d) Finite Volume Method

This question was addressed to me during an interview.

The query is from Numerical Methods topic in chapter Numerical Methods of Computational Fluid Dynamics

Answer 1

Right answer is (b) Boundary element method

The explanation is: In Boundary element method, the given boundary conditions are used to fit the boundary values into the integral equations. After this, using the boundary solutions, the solution for the interior nodes is carried out at the post-processing stage.
